[FMMISM] Chapter 90: Invader

"So, how did it come to this?"

After Ragna enjoyed a relaxing bath, he returned to his room and was shocked by what he saw.

"Good evening, Master."

Sitting casually on the edge of his bed was Morgan, who had changed out of her black and blue dress into a sheer, deep black nightgown.

The nightgown had straps that revealed her collarbone and shoulders, with a neckline that dipped quite low, showing tempting cleavage. Beneath its super-short skirt, she wore only black garter stockings that wrapped around her slender legs.

"Ugh... this is definitely crossing the line... It's quite different from what I imagined… this is truly a shameless outfit."

Next to Morgan, Artoria's face was flushed with a shade of red as she blurted out.

Artoria kept tugging at the hem of her pure white, almost thigh-high sheer nightgown. More captivating than her flawless, snake-like white arms were her well-trained, long legs, which were now clad in white garter stockings. On top of that, the tightness of the stockings accentuated her full, rounded thighs in an appealing curve.

Unlike the usual loose sleepwear, tonight's outfits were designed to showcase the perfect figures of the two sisters.

Morgan's black and Artoria's white nightgowns not only highlighted their graceful curves but were also somewhat transparent. Moreover, their pale skin appeared even more flushed, and the thin fabric made it almost unbearably difficult to look away.

While Ragna was taking his bath, it seemed the two sisters had already bathed too, emitting a faint fragrance.

"..."

Ragna stared at the breathtakingly seductive Morgan and Artoria, struggling to snap out of it.

"What's... going on here...?" Ragna asked slowly.

"It's a joint bedtime service from Britain's King of Knights and Fairy Queen." Morgan playfully touched her lips and smiled alluringly. "There will never be another man in this world, past, present, or future, who can enjoy such a service, y'know? Now you should understand who really knows you better."

'So this is the kind of trick she's pulling?' Ragna thought in surprise.

If she couldn't sneak ahead, she might as well drag the competitor down, showcasing Morgan's 'understanding of him' and getting back at her sister.

Ragna gasped, again struck by Morgan's terrifying tactics.

Ignoring Morgan's smirk, Ragna turned to ask Artoria.

"Just to clarify, Lancer, you were dragged here by Caster, weren't you?"

"...Yeah, I did say I wanted fair competition, but I didn't mean this… Ugh, this nightgown wasn't my choice but, I couldn't ignore her… Master, please don't keep staring at me..."

As Artoria replied quietly while blushing, she fidgeted with her fingers, her adorable demeanor in stark contrast to the imposing figure of the King of Knights she usually was.

While Artoria was still explaining at length, Morgan forcefully grabbed Ragna's hand, pushed him onto the bed, and pulled the blanket over the three of them.

On the left was the enchanting and flirtatious Fairy Queen, casting a leopard-like gaze at him.

On the right was the beautiful and charming King of Knights, nervously clutching the edge of her nightgown.

Ragna suddenly had a premonition that he might have a wet dream by morning.

"Alright, it's time to turn off the lights."

Morgan, lying on the bed, spoke to her sister on Ragna's other side.

"Yeah… turn off the lights."

Hearing her sister's words seemed like salvation for Artoria, who immediately sighed in relief, though she didn't let go of the edge of her nightgown.

"Good night, you two." Morgan said calmly before closing her eyes.

To Ragna's mixed feelings of relief and disappointment, she didn't make a move to assault him or further torment her sister.

With this, the three of them slept together in the large bed.

===

At the same time, a sudden, intense unease jolted Irisviel awake from her sleep.

'An enemy attack... someone has entered the castle...'

Just the fact that they managed to breach the castle without being detected by the bounded field in the forest meant that the enemy likely had 'Presence Concealment'—probably Assassin.

Irisviel propped herself up from the bed, threw on a coat, and made her way alone into the pitch-black castle corridor.

As the cold air stung her skin, it made her nostalgic for the nights she had spent being held by Ragna. On the chilly nights, the warmth and strength radiating from the small boy had given her an immense sense of security.

'No!'

Irisviel quickly shook her head.

Was she suffering from Stockholm syndrome?

Clearly, that boy was not only the one who kept her and her husband apart but had also taken Lancer away.

However, Ragna, despite saying 'Irisviel is now my woman', had never truly sullied her dignity.

"?!"

At this moment, a thought suddenly flashed through Irisviel's mind.

Was Ragna silently protecting her by staying in her room every night?

Irisviel bit her lip nervously, and a strange feeling suddenly arose in her heart.

'Anyway, I need to quickly notify them...'

As she sighed deeply with her head lowered, a warning sign flashed in Irisviel's mind.

"?!"

A tall man clad in a pitch-black priest's robe, with a short, commanding haircut, stared at her from the end of the dark corridor, his face stern.

Seeing this man, Irisviel coldly muttered his name.

"Kotomine Kirei..."

Kotomine Kirei, who should have long since withdrawn from the Holy Grail War after his Servant was supposedly killed by Archer, stood there.

"Oh? Lady Irisviel, I believe this is our first meeting." Kirei greeted calmly. "Even someone as noble as you recognize a nameless person like me?"

Irisviel realized her mistake and regretted it deeply.

"Since you know who I am, it's simple. Please come with me." Kirei continued.

'So that's what this is about...' Irisviel narrowed her eyes.

At first, she was puzzled as to why someone would be foolish enough to attack this place. After all, everyone knew that the master of the Einzbern Castle was the mysterious boy who had effortlessly defeated even the King of Heroes.

From the perspective of other groups, Lancer's Master, Irisviel, had become a captive of this mysterious boy.

Kirei's goal was to abduct her, the Lesser Holy Grail who had lost her Servant.

"To be honest, I was very disappointed when I learned of Emiya Kiritsugu's failure..."

Kirei rambled on there, but Irisviel couldn't absorb a single word.

She knew that the enemy was a battle-hardened Executor of the Holy Church.

Could she flee from him?

As the master of the bounded field enveloping the castle, escaping from this place wasn't actually difficult. If she went to Ragna's room, she could ask him for help and swiftly deal with the invader.

Without delay, Irisviel quickly sensed through the bounded field and discovered that Ragna was sleeping with Artoria and Morgan in the same bed.

Ragna was now holding them close, enjoying family bliss.

"?!"

When this information flashed through Irisviel's mind, a surge of nameless anger suddenly rose in her chest.

She immediately made a new decision regarding Kirei.

She wanted to kill the man before her, though, the reason was unclear even to her.

Was it to prove her own worth to the boy? Or did she not want to disturb the three of them who were sleeping blissfully?

Irisviel only knew she was very angry now.

She desperately needed to beat something to vent her frustration and anger.
