Chapter 1-5 - Preview of In DxD with Sign-In System!

I’m exploring ideas for a fanfic that could succeed [DxD: Transfer Student]. Here’s one concept I’ve been working on—share your thoughts in the comments!

I apologize that I couldn't publish all 10 chapters. However, each chapter is longer than the standard length. I also have another fanfic in mind, which I may release soon. The same apply to the remaining 5 chapters of this fanfic!

----

Chapter 1: Starting with a Rainbow-Grade Gift Bag

"Parents deceased, with money and a house… it really does fit my current situation."

As a newly-fledged transmigrator to this world, I should have been the envy of my peers. But compared to other transmigrators from my home planet, I was having a pretty miserable time of it.

"This is ridiculous. I've been in this world for 18 years already, so why hasn't my system cheat appeared?"

My name is Hibari Kyoya, and right now, my mood could be described as incredibly complex, with more than a hint of anxiety mixed in.

This is because I know all too well that I'm currently in a world called "DxD." According to my memories from my previous life, this world isn't just filled with Devils, Angels, Fallen Angels, and various pantheons of gods, but also Dragons. It's a world where gods vie for supremacy, and as a result, I'm constantly in extreme danger.

Even more distressing is the fact that I'm smack-dab in the center of this world's vortex of chaos: Kuoh Town, and specifically, Kuoh Academy!

To top it off, I'm even in the same class as one of this world's main heroines, Rias Gremory!

But even those factors alone, I could maybe handle with a bit of luck.

However, my investigations uncovered an even more serious problem: the protagonist of the original story, the host of the Red Dragon Emperor, Hyoudou Issei, is gone.

Not only that, but even the Student Council President Sona Sitri's peerage member, Saji Genshirou hasn't become a devil yet, either.

Saji is attending the academy normally, at least. But as for that pervert Hyoudou Issei, there are no traces of his existence anywhere, as if he never existed at all.

At first, I considered that maybe my arrival had caused a butterfly effect, leading to Hyoudou Issei's non-existence. So, I went to find Hyoudou Issei's original mother to learn more. But after her repeated confirmations, she insisted she did not have a son named Hyoudou Issei.

Although the disappearance of this lecherous protagonist made me a little uneasy, it also threw my original plans into disarray. But Hyoudou Issei's disappearance was already a fact, so no matter how much I worried, it wouldn't do any good.

Because even though this is the world of an anime, Kuoh Town is the Devil's headquarters. The younger sisters of two of the Underworld's Maou live here! Not to mention, Fallen Angels are extremely active in this town.

Soon, high-ranking Fallen Angel cadres will arrive to try and destroy Kuoh Town. Then there's the White Dragon Emperor, the Khaos Brigade, and many more dangerous matters to come. And as if that weren't enough, this world also has the looming threat of an invasion by Evil Gods.

When I first arrived in this wish-fulfillment world of anime, I swore I'd stand at the pinnacle of this world.

But now, all of that just seems like a pipe dream.

Ultimately, I'm just an ordinary student right now. I have no power to achieve my grand ambitions. DxD is full of beautiful girls, but I can only watch from the sidelines. All I want is to give them a safe and warm home. What's wrong with that? I can't help but feel incredibly frustrated.

Over the past decade or so since I arrived, I have tried to train and develop my potential. But no matter how hard I trained, I am still human.

In this world, without power, you can only live cautiously. Your life and death are at the mercy of those in power. I could be killed by a stray Devil or a Fallen Angel at any moment.

For a transmigrator like me, this reality was incredibly depressing.

"The new school year is starting soon, which means the main story is probably about to begin. I had considered trying to become a member of Rias or Sona's peerage, but I'm just a student with good grades. They probably wouldn't even give me the time of day."

It seems like I can only take things one step at a time.

"Ding! Sign-In System loading… 20%… 50%… 80%… 100%."

Just as I was lamenting my situation, a mechanical voice suddenly rang out in my mind.

After being stunned for a good ten seconds, I finally snapped out of it, feeling a surge of excitement. If it weren't for the fact that it was nighttime and I might disturb others.

Eventually, I managed to get my excitement under control and calm down a bit. I asked the system why it was so late.

"This system only awakens when the main storyline begins."

The system, 18 years late, answered my question honestly.

"You damn system, do you have any idea how I've been living these past 18 years? Do you? I've been constantly on edge, terrified that I'd run into a stray Devil and get my ass handed to me!"

But in the end, I calmed myself. "Sign-In System? Introduce yourself."

"This system's function is as the name suggests. By signing in, you can receive rewards. You can sign in at specific locations or complete system-issued tasks to earn rewards. Sign-ins and tasks are graded as White, Green, Red, Black, Purple, Gold, Violet-Gold, and Rainbow."

"Hmm, the system's functions are pretty straightforward. It suits me."

My mood was now completely different from the anxiety-ridden state I was in just an hour ago.

"Hey system, I can't just go around looking for people or places to sign in, right? My memory isn't perfect. I don't know everything. Do you have a map or something for marking locations?"

If this Sign-In System only allowed me to sign in at specific locations, that would be very limiting. I couldn't just run around the whole world, could I?

The system didn't answer directly. Instead, a screen suddenly appeared before my eyes, visible only to me.

The screen displayed many points where I could sign in, even marking locations in Heaven, Hell, and the Dimensional Gap. Although, I didn't have the power to go to those places to sign in yet.

I zoomed in on the screen and located Kuoh Town. In an instant, I saw many question mark sign-in locations. I wasn't surprised. This place is where many of the main heroines gather. It would be strange if there weren't any sign-in locations here.

After examining it for a while, I dismissed the screen.

Suddenly, I remembered something and jokingly asked the system, "Hey system, you were 18 years late. Don't you have a newbie gift bag or something? I've seen other systems with those. You don't have one, do you?"

System: "…"

"Ding! Congratulations to the host for receiving the Newbie Gift Bag: Rainbow-Grade Sign-In Gift Bag."

The system's mechanical voice rang out again, and I froze in shock!

"Holy crap! System, you're the best! It's actually the highest-grade Rainbow-Grade Sign-In Gift Bag!"

My face was now permanently etched with an expression of pure joy.

Honestly, I hadn't expected my system to be so generous. I was originally planning to haggle with it, maybe get a small ability to improve my situation. But now, all I can say is, "System, you're amazing!"

Based on what I had observed on the system screen earlier, the strongest being in DxD, the True Red Dragon God Emperor, only had a Violet-Gold grade sign-in. I'm guessing the Infinite Dragon God, Ophis, is probably a light Violet-Gold grade sign-in!

So, if I'm getting the highest-grade Rainbow-Grade Gift Bag, I've definitely hit the jackpot!

Chapter 2: Azure Dragon's Power Stuns the World

Just then, a rainbow-colored card appeared before me, radiating a brilliant light.

"System, how do I use this?"

After examining the card carefully, I asked the system.

My heart was pounding with excitement, and my voice trembled slightly.

"The host needs only to lightly touch the card with their finger to open the gift bag."

Even though the system's mechanical voice was devoid of emotion, to me it sounded like the most beautiful music in the world.

Suppressing my excitement, I slowly extended my trembling right hand, and my finger lightly touched the rainbow-colored card.

Suddenly, the card emitted a blinding light that scattered in all directions. A figure flew out from the card and soared into the sky above Kuoh Town.

When the light faded, a giant dragon's phantom, radiating an aura of pure terror, appeared before me.

"Ding! Congratulations to the host for opening the Rainbow-Grade Gift Bag and obtaining the soul of one of the Four Symbols, the Azure Dragon!

(Its World King - Kurma From Mondaiji)
(On VS Battles Wiki, it is classified as a 2-C Multiversal Being!)

Note: The Azure Dragon is more powerful than Kouryuu, one of the Seven Great Demon Kings of the Little Garden who possesses the power of a True Dragon! Due to the host's current weakness, it can only be used once for a short time. The duration of use and the power it can exert will change along with the host's own strength."

The system's voice had barely faded, and I was already completely stunned!

One must understand, The Azure Dragon was called the "World King" or the "World Dragon." The Bull Demon King called him "Kuu-Chan." A Dragon that carried the world on his back, traversing the sea of stars.

...

...

From what I understood, the Little Garden had a vast worldview, but there were very few beings in the double-digit ranks! The exact power level of a single-universe entity was unknown, but in this world, they were absolutely invincible!!

In front of the Azure Dragon, The True Red Dragon God Emperor, wouldn't even be worth mentioning. I could probably kill him with one punch…

(Search : His Highness Mondaiji Avatāra Gift Fandom)

"Host, do you wish to merge with the soul of the Azure Dragon?"

The system's mechanical voice interrupted my thoughts, bringing my attention back to the Azure Dragon's phantom in the sky above Kuoh Town.

"System, merge me with the Azure Dragon's soul."

I didn't think twice. I immediately told the system to merge me with the Azure Dragon's soul. My eyes were glued to the giant dragon's phantom above.

"Ding! Dragon soul fusion beginning…"

As the system's voice sounded, the dragon's phantom emitted a brilliant beam of light that instantly enveloped me.

As the Azure Dragon's soul merged with me, I could clearly feel my life essence undergoing a sublimation, an evolution. But what I didn't know was that the outside world was undergoing earth-shattering changes.

The Azure Dragon's phantom spanned the entire DxD world. No matter where you were, you could clearly see the Azure Dragon's phantom.

Even the Great Red, soaring through the Dimensional Gap, could clearly sense the intimidating power of the dragon's phantom. He was utterly astonished.

A being more powerful than a double-digit from Little Garden. The Azure Dragon. Just a tiny bit of its power leaking out was enough to make the entire world tremble, as if it were about to shatter.

Because of this, even the Great Red had to use his own power to stabilize the world.

And the Fallen Angels and Devils residing in Kuoh Town wore expressions of absolute horror!

"What the hell is going on?"

Rias Gremory, stared blankly at the dragon's phantom in the sky. She could clearly feel the fear emanating from the depths of her soul.

Her best friend, Sona Sitri, along with their peerages, felt the same way.

Their faces were pale, their pupils constricted, and they were filled with terror as if they were about to die at any moment.

As high-ranking Devils, they had seen many Dragon Kings. They hadn't seen the two Dragon Gods, but at least they'd heard about them. However, the dragon's phantom in the sky was unlike any dragon they knew. It was as if it had appeared out of thin air. It was all too surreal.

These two Maou's sisters wanted to quickly relay the information to their families, but the pressure on their souls made them unable to move.

...

At this moment, the Four Great Maou in the Underworld were also staring at the sky in terror.

"What is this? This dragon's phantom's power completely surpasses that of a Dragon God."

They could clearly feel that, with the appearance of this dragon's phantom, they were like weak ants. Even their internal magic power had stopped circulating.

As one of the few remaining Super Devils in the Underworld, Maou Lucifer understood that even facing the Infinite Dragon God wouldn't cause such a feeling of powerlessness.

But in the face of this dragon's phantom, he couldn't muster a single thought of resistance, because this dragon's phantom could definitely erase him with a single thought.

....

It wasn't just the Underworld. Even the main gods of the various pantheons, such as those in Hell, the Greek pantheon, and the Norse pantheon, were staring at the dragon's phantom in astonishment.

And, of course, the various Dragon races were reacting, too. The current Five Great Dragon Kings, the evil dragons, and the lawless Two Heavenly Dragons, the Red Dragon Emperor and the White Dragon Emperor, looked at the dragon's phantom in the sky with reverence in their hearts. Their power was on a completely different level from that of the phantom.

Just then, the Azure Dragon's soul completely merged with me.

The Azure Dragon's soul suddenly let out a dragon's roar that made the powerhouses of the various pantheons cough up blood.

Then, the dragon's phantom disappeared from the sky above Kuoh Town. The main gods of the various pantheons all looked towards Kuoh Town with grim expressions. They then issued a series of orders, their intentions unknown.

For example, the originally troublemaking Indra sent a message to Cao Cao, asking him to maintain a low profile recently.

In a certain unknown location, a silver-haired loli appeared. It was none other than the infinitely cute Dragon God, Ophis. She stared blankly at the sky and muttered.

"A strange Dragon God whose power far surpasses mine and the Great Red's… I wonder if you can help me reclaim my silence?"

....

Chapter 3: First Sign-In, Three Types of Haki

Slowly opening my eyes, I could clearly feel the Azure Dragon's soul power within me, but I couldn't use it. I was still too weak. If I tried to activate the Azure Dragon's power now, I'd probably explode in a matter of seconds.

"Still, as a life-saving trump card, it's more than enough."

With that thought, I went back to my room, suppressed my excitement, and slowly closed my eyes, drifting off to sleep.

The next morning, as I stepped onto the grounds of Kuoh Academy, the system's voice rang out.

"Ding! Detected special sign-in location: Kuoh Academy. Red Grade. Sign in?"

"Kuoh Academy is only Red Grade? Well, I guess that makes sense. It is the gathering place of the main characters, after all."

I muttered thoughtfully to myself.

Then, I mentally commanded, "System, sign in."

"Ding! Congratulations to the host for successfully signing in at a Red Grade location. Reward: Top-Tier Three Types of Haki."

It was actually Top-Tier Three Types of Haki! I was a little surprised.

In the world of One Piece, Top-Tier Three Types of Haki was incredibly powerful. Top-Tier Observation Haki could even allow you to glimpse into the future.

Top-Tier Armament Haki could be applied to the body or weapons, and the advanced form, Ryou, could even destroy an enemy from the inside, causing devastating damage.

And Top-Tier Conqueror's Haki, with its Conqueror's Coating, was even more powerful.

All in all, I was pretty satisfied with getting Top-Tier Three Types of Haki from a Red Grade sign-in.

The only problem was that, although I had obtained Top-Tier Three Types of Haki, my physical condition was still that of an Average Human. More importantly, I had no combat experience, so I couldn't unleash its full potential.

But then I thought about it some more and cast aside my worries. As long as I kept signing in, I could make up for these shortcomings.

I mentally called up my status screen:

Host: Hibari Kyoya

Physique: Average Human

Magic: None

Abilities: Top-Tier Three Types of Haki, Azure Dragon Soul Power (Sealed)

Inventory: None

As soon as I entered the classroom, the system issued two new sign-in tasks.

"Ding! Discovered character sign-in target: Rias Gremory. Task Condition: Defeat her and make her acknowledge you."

"Ding! Discovered character sign-in target: Akeno Himejima. Task Condition: Tame her and make her fall for you."

Looking at the two tasks, I couldn't help but fall silent.

You've got to be kidding me, system. With my current strength, without using the Azure Dragon's power, how could I possibly be Rias's match? And Akeno? Don't let her gentle appearance fool you. She's got a seriously sadistic side. If I'm not strong enough, I'll probably be the one getting tamed instead!

Just thinking about it made me shudder.

Suddenly, Rias felt a gaze on her and turned to see me looking her way.

My grades at Kuoh Academy were naturally always at the top. Combined with my good looks, I was quite the campus celebrity. So, Rias was familiar with me. It was precisely because she knew me that she felt a little puzzled.

Just as Rias was lost in thought, a seductive voice teased in her ear.

"Ara ara, Rias, you've been staring at Hibari-san. Could it be that you've taken a liking to him?"

Rias's heart skipped a beat, and she turned to see Akeno smiling playfully at her.

"Well, considering it's Hibari-san, who always gets top marks despite sleeping in class, and is so incredibly handsome, it wouldn't be surprising if Rias fell for him."

Akeno continued with a teasing smile.

"It's just a shame that I also have a bit of a crush on him. But if it's Rias, I guess I'll have to give up."

A faint blush appeared on Rias's cheeks. She knew Akeno was just joking, so she simply rolled her eyes and replied.

"I was just a little surprised. It feels like Hibari-san's aura has changed significantly. I can't help but feel a sense of pressure just from looking into his eyes."

Akeno was a little surprised to hear Rias's words. After all, Rias at level of a High-Class. For her to feel pressure from me meant something was definitely different.

It made sense, though. I now possessed Top-Tier Conqueror's Haki, the Haki of a true king. However, I couldn't control it yet, which was why my aura was leaking out like this.

Akeno then asked Rias if she wanted to investigate what had happened to me.

But after thinking it over, Rias told Akeno to drop the investigation. The events of last night with the dragon's phantom, along with her brother's warning this morning, had left her feeling stressed.

But what Rias could never have guessed was that the cause of this strange phenomenon was none other than me, and I was currently sitting just a few feet away from her.

When the dismissal bell rang, I slung my bag over my shoulder and headed out of the school gates.

And just at that moment, I happened to run into a certain emotionless, petite girl walking in the opposite direction. It was none other than Rias's Rook, Koneko Toujou.

"Ding! Discovered sign-in target: Koneko Toujou.
Task Condition 1: Defeat her at a video game! Reward: White Grade.
Task Condition 2: Give Koneko Toujou a head pat! Reward: White Grade.
Task Condition 3: Resolve the conflict between Koneko Toujou and her sister, Kuroka Toujou! Reward: Red Grade."

I was surprised to see three sign-in tasks pop up for Koneko all at once.

Task 1 didn't seem too difficult. Even though Koneko was a gaming expert, in my past life, I was a top-tier gamer, Beating Koneko should be a piece of cake.

But Task 2... seriously, system? You're getting cheekier by the day. Koneko's head isn't something you can just touch. If I tried to pat her head, I'd probably get punched into a wall, so hard I'd be impossible to get out!

As for Task 3, it shouldn't be too hard in the future, either. The conflict between the sisters is really just a misunderstanding. Once I get stronger, I can just grab Koneko's sister, Kuroka, and have them clear things up.

Then, I slowly walked over to Koneko.

Koneko, seeing me approach, stared at me intently.

Meanwhile, a cold sweat started to form on my forehead. After all, being stared down by an expressionless, petite girl would make anyone nervous.

"Is there something you need, Hibari-senpai?"

"Ah… well, actually, I was wondering if you'd like to go to the arcade with me to play some games."

After a moment's thought, I calmly explained my intentions to Koneko.

Hearing my words, a flicker of surprise finally appeared on Koneko's usually blank face. She hadn't expected the top student in the school to invite her to play games. But she was also quite happy about it, so she agreed.

And so, Koneko and I had an intense battle at the arcade. Don't get any weird ideas, we were just playing video games. But the end result left Koneko feeling utterly defeated.

Koneko stared at me in disbelief, her eyes wide with shock. She hadn't expected this shut-in senior of hers to be able to beat her at video games.

"Don't worry, Koneko-chan. I'm a genius, after all."

As I comforted Koneko, I slowly extended my hand and gently patted her head.

Instantly, a blush appeared on Koneko's cheeks. She then raised her small, soft hand and slapped my hand away, her face cold.

"Pervert Hibari-senpai."

"I'm really sorry. I just thought you were so cute, I couldn't help myself. To make it up to you, I'll treat you to more games or dinner sometime."

I sincerely apologized to Koneko and asked for her forgiveness.

Hearing my apology, Koneko's expression softened slightly. But she was still exasperated by my thick-skinned behavior. In the end, she chose to forgive my perverted act.

"If you do it again…" Koneko raised her clenched fist and shook it menacingly at me.

"…"

"Don't worry, there won't be a next time. Well then, Koneko-chan, I'll be going now. See you tomorrow." I broke out in another cold sweat and quickly made my exit.

After watching me leave, Koneko returned to her usual emotionless self and headed towards the Occult Research Club.

Chapter 4: Power Upgrade, Brutal Destruction of a Low-Class Stray Devil

Slowly opening my eyes, I could clearly feel the Azure Dragon's soul power within me, but I couldn't use it yet. I was still too weak. If I tried to unleash the Azure Dragon's power now, I'd probably explode in a matter of seconds.

"Still, it's more than enough as a last-resort, life-saving trump card."

With that thought, I returned to my room, suppressed my excitement, and slowly closed my eyes, drifting off to sleep.

The next morning, as I leisurely walked towards Kuoh Academy, I asked the system about the completion status of my tasks.

"Patting Koneko Toujou's head task completed. Reward: Zanpakuto: Zangetsu (Bankai mastered). Defeating Koneko Toujou at a video game task completed. Reward: Mastered Rokushiki."

Hearing the system's rewards, even though I remained outwardly calm, my heart was bursting with joy.

I now had Mastered Rokushiki along with extensive combat experience, which, combined with the Top-Tier Three Types of Haki I received earlier, represented a massive leap in my power.

As for the Zanpakuto Zangetsu, I was a bit surprised but also thrilled. Back in my previous life, when I watched Bleach, I always fantasized about owning a Zanpakuto.

I just hadn't expected the system to reward me with the Zanpakuto of Bleach's protagonist, Ichigo Kurosaki.

"System, can Zangetsu stay in its Bankai form permanently?"

I wasn't really a fan of Zangetsu's Shikai form, which was a giant cleaver. I preferred the sleek, slender katana form of its Bankai.

"Acknowledging host's preference. Zangetsu's form is now permanently set to Bankai. The host can freely switch between Zangetsu's forms according to their will."

Hearing the system's solution, I was in a great mood. I even started humming a tune on my way home.

And just at that moment, the system's voice rang out in my mind again.

"Ding! Detected a nearby Stray Devil. Killing it will yield a White Grade reward."

After receiving the system's task, I felt incredibly fortunate. Fortunately, my golden finger had arrived yesterday, otherwise, I might have ended up as this Stray Devil's next meal.

Then, a surge of excitement coursed through me. I could finally experience my first real battle!

When I reached the depths of the alley, I saw a scantily clad woman.

She was wearing a loose robe, holding a bottle of liquor, her long black hair was wet, and a sickly sweet, heavy fragrance wafted from her. I examined her closely and saw that she was a seductive, enchanting woman.

The woman also noticed me, and her eyes lit up. She smiled seductively and walked towards me.

"Well, well, well, what a handsome young man we have here. How about a drink? Let's do something fun, shall we?"

The woman winked at me suggestively and spoke in a seductive tone.

Facing this clueless Stray Devil's advances, I raised an eyebrow. A playful idea popped into my head. I decided to toy with her a bit before finishing her off. So I said:

"Sure, but I'm afraid you might have spiked the drink. A guy's gotta protect himself when he's out and about, you know? How about you take a swig first?"

The Stray Devil was momentarily taken aback. Could this kid have seen through the poison in my drink? But then she shrugged it off. What did she have to fear from a student? She wasn't afraid of poison anyway. Her favorite thing was to watch humans slowly get devoured while suffering from the effects of her poison. Just thinking about it made her heart race, almost like a climax.

The Stray Devil immediately picked up the bottle and took a large gulp, then handed it to me, saying:

"There, see? I drank plenty. Now it's your turn, handsome."

But I didn't take the bottle. Instead, I crossed my arms and looked at her with a playful smirk.

Seeing my expression, the Stray Devil grew impatient and urged me:

"What are you looking at, handsome? Drink up! After you're done, I'll show you something really good."

Seeing that I was still unmoved, the Stray Devil finally snapped. She revealed her true form and roared at me with a ferocious face.

"You little shit! Drink! Why aren't you drinking? If you're not going to drink, then just die!"

The woman had now transformed into her true Stray Devil form: a monstrous spider with six eyes on her upper body and six legs on her lower body.

I looked at the mentally broken Stray Devil with disgust.

"What's wrong? Showing your true colors already? And you call yourself a mature Stray Devil? With that attitude? Go back and train some more. Although, it's a shame you won't get the chance."

Hearing my taunts, the Stray Devil finally understood. This damn human had known her identity all along and was just toying with her! Rage consumed her.

"I'm going to tear you to pieces!"

In an instant, the Stray Devil lunged at me, her six eyes spinning wildly, her blood-red claws reaching straight for my neck.

But I remained exceptionally calm. With my Top-Tier Observation Haki, I could easily dodge the Stray Devil's attacks. But I didn't plan on dodging. I wanted to test my current strength by taking the attack head-on.

I activated Iron Body, hardening my entire body. But then I suddenly remembered a saying from my past life: Iron Body = standing still = taking full damage = instant death.

Therefore, cherish life, stay away from Iron Body. Besides the Marine Hero Garp, everyone else who used Iron Body seemed to have a misplaced sense of confidence, leading to their swift demise.

Thinking of this, I suddenly felt a little panicked, afraid that I might also fall victim to this Iron Body illusion and end up dead. So, I quickly coated my entire body with Armament Haki, turning my skin pitch black.

Crack!

The Stray Devil's claws shattered on impact, and she let out a pained shriek.

"Argh! You damn brat!"

I ignored the Stray Devil's howls and used Flash Steps to retreat a dozen steps. I touched my neck and thought back to the Stray Devil's attack.

"It seems that with my current Iron Body and Armament Haki hardening, I could probably withstand a full-force attack from a Mid-Class Devil."

My gaze suddenly sharpened, like a honed blade.

"Haki-Coated Tempest Kick: Infinite Storm!"

I softly uttered this incredibly chuunibyou-esque attack name and used one of the Rokushiki, Soru, to disappear from my spot.

In an instant, a dozen afterimages appeared around the Stray Devil, accompanied by a raging whirlwind. It was as if I were at the center of a tornado.

Numerous cracks appeared on the surrounding walls, as if they had been slashed. In the blink of an eye, I appeared above the Stray Devil.

Snap!

After returning to my original position, I walked directly to the backpack I had thrown on the ground earlier.

Even though this was my first real fight, I felt that my mastery of the Rokushiki and Haki was probably not much inferior to a Marine Admiral's.

After all, I had the system's gift of rich combat experience. So the battle itself wasn't difficult. In fact, I might even be a bit of a natural... I couldn't help but feel a little smug.

But as I picked up my backpack and prepared to leave, the Stray Devil's eyes were filled with mockery. She sneered:

"Hahaha, I thought you were something special. Turns out you're just all flash and no substance… How utterly weak. In that case, I won't hold back any-"

...

"Tsk, You still don't get it, do you?"

I stopped and turned my head, looking at the Stray Devil with a calm gaze.

"You're already a dead woman. Well, a dead devil, to be precise."

"What are you talking about…?"

The Stray Devil didn't even get to finish her sentence.

Splat!

The Stray Devil's body collapsed, her limbs severed and scattered across the ground. A thin line appeared on her neck, and her head rolled away like a ball.

Blood splattered everywhere, raining down like a gruesome shower. Only then did the Stray Devil realize... that she had been cut to pieces by this brat!

Thud!

Her body hit the ground.

Looking at the gruesome scene, I felt a little troubled. But after a moment's thought, I decided to leave this mess behind.

Surely Rias or Sona would take care of the cleanup, since they were the ones in charge of this town. Besides, they're going to be my women in the future. It's only right that they help their husband out a little, right?

"Ding! Task completed. Reward: Perfect Rumble-Rumble Fruit (weakness to water removed)."

"I hit the jackpot! It's the Rumble-Rumble Fruit without any weaknesses!"

The Rumble-Rumble Fruit was a Logia-type Devil Fruit from One Piece. It allowed the user to transform into lightning, making them immune to physical attacks, most energy attacks, and non-Haki attacks. It also granted the user the ability to freely generate and control electricity.

They could also use electric waves to enhance their Observation Haki, and they could use the fruit's power to teleport. It possessed ridiculous destructive power.

And this reward had even removed the Devil Fruit's weakness to water! Although I couldn't fully utilize the Rumble-Rumble Fruit's power yet, it was more than enough for self-defense in the short term. It seemed like my luck had finally turned.

Just as I was happily fantasizing about a future surrounded by beautiful women, a magic circle suddenly appeared before me. Several familiar figures slowly emerged from it, causing me to feel a mix of surprise and annoyance!

"Here comes trouble."

...........

Chapter 5: Rejecting Rias's Invitation

Just as I was still marveling at my new powers, the figures of the three people in the magic circle became clear.

It was Rias and her two peerage members, Koneko Toujou and Akeno Himejima.

The three of them fell silent as they took in the gruesome sight of the dismembered Stray Devil. Akeno was the first to speak, turning her gaze towards me.

"Ara ara, if it isn't Hibari-san? I didn't realize you were a Devil, too. But... you have a human's aura!"

After confirming that I was human, Akeno was visibly shocked. She couldn't imagine that the seemingly ordinary shut-in from her memories possessed such power.

Even the usually expressionless Koneko had a flicker of shock in her eyes. As for Rias, the initial surprise on her beautiful face quickly faded, replaced by a look of intrigue as she studied me.

"Hibari-san?"

Seeing the expressions of the three girls, I quickly realized that hiding was no longer an option. So, I casually walked up to them.

The quiet alley was bathed in the bright, silvery light of the moon. A gentle breeze blew past, carrying a slight chill.

The three of them silently surrounded me. Finally, the ever-impatient Akeno broke the silence.

"Ara ara, no wonder Rias said you'd changed a lot in the past few months. I never expected you to have such strength, Hibari-san."

"Hibari-san… you have to tell me your secret~ I'm just dying to know~"

Akeno placed her delicate hands on my shoulders and whispered softly into my ear, her warm breath tickling my skin.

A sweet fragrance wafted into my nostrils, and I could feel her breath on my ear, sending shivers down my spine. I turned my head to see Akeno looking at me with a tender, smiling gaze.

In an instant, I felt my blood rush, and my mind filled with endless fantasies.

That damn Akeno, she's such a sadist, teasing me like this. When I finally claim you, I'll be sure to get my revenge! Vixen!!

Rias, seeing this display, seemed to have come to a conclusion, but she still asked, "Hibari-san, if you don't mind, could you explain what happened here?"

I sighed and explained, "Isn't it obvious? This Stray Devil tried to seduce me and then eat me. I had no choice but to defend myself and kill it."

"I assure you, I'm a law-abiding, model citizen!!"

Rias looked at the dismembered Stray Devil and then gave me a playful, skeptical look. If it weren't for the gruesome scene before her, she might have actually believed me. After a moment's thought, she decided to trust me.

But even though Rias believed me, Koneko had already moved to stand protectively in front of her, clearly on guard against me.

Rias gently patted Koneko's head and said with a smile, "It's okay, Koneko-chan. Hibari-san doesn't mean us any harm."

Seeing this, I teased, "Hey, Koneko-chan, we're gaming buddies, aren't we? I even invited you to play games earlier. It's a bit hurtful that you're treating your friend like this."

Hearing Rias's reassurance and my teasing, Koneko lowered her guard, but she didn't move from her position in front of Rias.

"Sorry, Hibari-senpai."

Rias looked at Koneko, standing protectively in front of her, with a look of pure affection in her eyes.

I waved my hand dismissively, indicating that I was just joking.

Suddenly, Akeno turned to me, gently caressing my cheek with her right hand. "Ara ara~ Hibari-san, you still haven't answered my question~ It's not very gentlemanly to leave a lady hanging, you know?"

Facing Akeno's renewed inquiry, I looked at her with a mischievous glint in my eyes and said, "Akeno, you haven't told me about your being a Devil, either. But this is a secret of the Hibari family, passed down only to the women of the family. If you want to know, you'll have to become my wife. So, are you interested?"

In response to my teasing, Akeno pretended to be shy, a blush spreading across her cheeks. "Ara ara, Hibari-san, you're such a bad boy! Sob sob... All I did was ask a question, and now you want me to be your girlfriend."

But I didn't respond to Akeno's words. Instead, I shifted my gaze to Rias.

Seemingly having thought of something, Akeno looked at Rias and me with a playful smile. "Ara... could it be that Hibari-san has taken a liking to Rias? Well, that's understandable! But what about me? Are you planning to abandon me? You just said you wanted me, and now you are going after Rias to live happily ever after? All men are the same! Right, Rias?"

The beautiful girl with the black ponytail, feigning tears, turned to complain to the equally busty, crimson-haired beauty beside her.

Rias and I both sighed helplessly at Akeno's dramatic performance.

"Stop pretending, Akeno. I know your personality all too well. You can't fool me."

As soon as I said that, Akeno immediately stopped her fake crying and pressed her finger to her lips, her eyes full of playful interest in me.

"Ara, Hibari-san, you seem to know me very well. But we haven't really interacted much. Why do you say that?"

I stared intently at Akeno and said softly, "Because I've always been watching you, Akeno. I've always liked you, deeply! That's why I know everything about you!"

Hearing my bold, almost confession-like words, even the usually sadistic Akeno blushed, her eyes darting away, unable to meet my gaze.

Rias, watching this exchange that seemed almost like flirting, was utterly bewildered. She then chuckled softly, covering her mouth with her hand.

And to my confusion, I noticed that Koneko was now glaring at me with a look of resentment. Could she be... jealous?

I spoke again, "Of course, I also like the captivating Rias, and my cute and petite underclassman, Koneko-chan, too."

Hearing my words, Akeno giggled and whispered in my ear.

"Ara ara, such a bold declaration." Akeno slowly returned to Rias's side.

But Koneko was now staring at me with an unfriendly gaze, her face full of disgust. "You're getting more and more perverted, Hibari-san."

"A gentleman appreciates beauty without being lewd, and is romantic without being vulgar. How can that be called perverted, when it comes to men?" I turned to Koneko and tried to defend myself. "Koneko-chan, you should call me a gentleman, not a pervert. Understand, Koneko-chan?"

Even though she understood what I meant, it didn't stop Koneko from looking at me with utter disgust.

"Since Hibari-san is so fond of Akeno, how about becoming my peerage member?"

Seeing how well I got along with her peerage members, and considering my strength as a human, as well as the increasingly tense situation, Rias decided to try and recruit me.

"If you agree to become my peerage member, Hibari-san, you can spend a lot of time with Akeno~~ Of course, you'll have to be mindful of the time and place when you're together. How about it? Are you tempted?"

"Ara~~ Is Rias abandoning me? Even though we are the best of family, this is truly heartbreaking. Sob sob..." Akeno pretended to cry after hearing Rias's words, but she didn't actually object.

"Although your offer is very tempting, Rias," I paused, then pointed my index finger to the sky and declared, "why would I give up the entire forest for just one tree? Therefore, I refuse."

Koneko: "…"

Akeno: "…"

Hearing my bold declaration and subsequent refusal, Rias was momentarily speechless.

She shot me a frustrated glare, but deep down, she felt an even stronger desire to have me, to tame me thoroughly.

And so, after I promised to visit the Occult Research Club sometime, Rias finally let me go.
