“Oh, good morning, Cranel-kun!”

Bright.

Too bright.

The morning has just begun, but my new Sensei is shining too brightly!

“Jeez, you’re going to make me blush, if you look at me like that.” Nagisa-sensei laughed and shook his head, as she gestured for me to take a seat at the table. In a few moments, he had breakfast set on the table of our little home beneath the church. Our goddess, Hestia-sama, was already seated at the table and eating fresh bread with eggs. “C’mon. A full stomach is a nice to have. While you can fight without it, you’ll fight better with it! It’s too early for your to train to fight like that!”

All those words were said in a perfectly chipper voice, free of any ill intent whatsoever, to the point that I barely took note of the fact Nagaisa-sensei was talking about fighting on an empty stomach.

“Heh, for your perceptiveness, I award you one Sensei Point!” With a move my eyes could barely follow, my Sensei stuck something to my head, which fell into my hand the second I blinked. It was a lethal, speedy move that could’ve ended my life in an instant, like it did so many monsters, yet I hadn’t been able to react to it at all. “Get enough Sensei points and I’ll teach you something cool, Bell-kun!”

“But nothing too dangerous, Sensei!” Hestia-sama spoke contently through a mouthful of fried egg and bread. Nagisa-sensei simply laughed at her words, saying nothing, and earning her ire while scratching his cheek. “I’m not hearing a yes, Nagisa-sensei…”

“Well, Hestia-sama, dangerous is very relative. For example, I’m far more dangerous than most monsters, but you’re fine with Bell-kun spending time with me, right? Hehe.” Again, despite saying dangerous words, which reminded me of how my teacher tore through the Dungeon’s monsters with ease, plucking out hearts and crystals with single, efficient, and fearsome movements, he didn’t make me feel afraid of him at all. “I might not be able to reach Mach 20, but I’m pretty strong!”

I didn’t know what Mach 20 meant, but I’d be scared of anyone who Sensei says is stronger than him.

“Now, now, Bell-kun, it’s time for breakfast. Not worrying about creatures that that can easily destroy entire worlds.” Eh? What was that? Just what was said in a cheerful, calm tone that didn’t trigger the slightest bit of fear in my heart, but I feel should’ve? Something about the world being possibly destroyed? “You know, we’ll be very late, and Aina will be very unhappy with you, if we are.”

“Hm? Why would his Guild Advisor be unhappy with him for being late?”

“NO REASON, HESTIA-SAMA!” I lowered my guard too much, and didn’t focus enough at the same time! Sensei’s smile is honest, and it’s reaching his eyes, but he’s undoubtably sadistic if you don’t do things properly! “Thank you for the meal, Sensei! I’ll clean the dishes, and the pans, so you can go ahead!”

“Thank you, Bell-kun. Make sure to do everything nice and properly, so that you don’t have to do it again, okay?” Sensei’s smile and words were perfectly normal. Hestia-sama even agreed to them with a nod and her own bouncy smile. However, the words weighed down upon me like armor made of lead, and ai felt a cold sweat break across my body. Without a doubt, Sensei was telling me that I needed to put more effort into practicing what he taught me. I should be alert and oriented at all times, so that I don’t lose my life. That’s one of the first lessons of being an assassin. “Make sure to check your equipment, okay? I made a little sabotage to something, and you need to find it and fix it before you meet me outside, or we won’t be going to the Dungeon today.”

“Yes, Sensei! I’ll do that!” I stood straight and gave a small bow at his words. Despite hovering over the stove and cooking, he somehow managed to pat my head, while flipping an egg over to cook perfectly. He managed to do it more than three paces away from where I stood and didn’t look like he moved at all, even though I still felt his touch on my scalp. “Thank you for the meal, Sensei.”

“Heh, you’re welcome, Bell-kun. Be sure to get ready for today properly, okay?”

…​

Assassin.

I didn’t know what the word meant, until Nagisa-sense walked into the Dungeon with me.

It meant being somebody with every talent possible in order to able to kill a target.

A person who has devoted their entire lives to expanding a select series of special skills into a razor’s edge, so that those skills can be used to end lives. As long as you can use a skill to that respect, you must train it to its utmost end, in order to achieve the goal of taking a life.

However, that doesn’t mean you have to actually end lives.

Even though Sensei easily destroys every monster that he comes across, I can tell that he’s not a monster… or, well, maybe that’s he wants me to think.

He’s strong, fast, skilled, smart, and incredible.

Looking at him like a target, as someone who I must be able to “kill’” makes me feel like an ant that’s supposed to destroy a Kami-sama.

And, it would be impossible, if he wasn’t helping me every day.

From reading, writing, mathematics, and many other skills, as well as plunding into the Dungeon to defeat monsters, he’s building me up. From the way I think, to the way I move in battle, and even the way I speak, he is correcting, changing, and improving upon me. Everyday, he either teaches me something new, or makes me work on what he asked me to the day before, and I feel myself changing.

Slowly, but surely, I’m becoming someone who can kill Nagisa Shiota.

And, by becoming that person, I can achieve greater success in all other aspects of my life, thanks to my Sensei.
