"B-But..." Irisviel's fair face flushed a deep crimson. She looked ashamed, but she couldn't bring herself to scold him or lecture him that a boy his age shouldn't have such thoughts. What made her feel even more mortified was... she was actually quite happy about it? Irisviel, oh, Irisviel, what's the difference between you now and that lewd, wicked woman Aoi Tohsaka who corrupted Jiuan?
But in the end, Irisviel still couldn't say the words of reproach or education. She only whispered, "Why? Weren't we supposed to be finding that Assassin? Why are you suddenly talking about this?"
Lin Jiuan, of course, couldn't admit that he was lusting after her body and the rewards it would bring. "Because if we do that kind of thing, the Assassin might think we've let our guard down and look for a chance to kill us. Otherwise, with me here, he would never dare to make a move on you."
Seeing his serious expression, which contained not a trace of lust, Irisviel believed him. "But... we shouldn't be doing this." Her voice grew smaller and smaller, her head bowed so low it was about to be buried in the two snowy mountains on her chest.
"Mrs. Irisviel, can you just do it as a favor to me, please?"
"B-But..."
"Or does Mrs. Irisviel hate me?"
"No! I like Jiuan very much!" Irisviel quickly looked up and saw his clear eyes, which were completely devoid of any impurities and filled only with a desire to provoke the Assassin. She bit her lower lip, hesitated for two and a half seconds, then turned her head away in shame.
"...Don't tell anyone."
As an outstanding assassin, Kiritsugu Emiya was very patient. Even though the sudden arrival of that evil little brat had interrupted his assassination plan against Irisviel, he was not in a hurry. He had already successfully infiltrated the Einzbern castle. Even if Lancer was killed by the Einzbern's Servant, and even if she returned, she wouldn't detect him hiding in the shadows of the castle. There would always be a moment when she would leave Irisviel's side, and that would be his chance to strike.
And once he killed Irisviel... not only would he eliminate Artoria, thereby weakening Lin Jiuan's support, but by using his 'Severing' Origin on this 'Lesser Grail', he could completely destroy this derailed Holy Grail War and fulfill the mission given to him by the Counter Force. It was killing two birds with one stone. This was why he had agreed to Tokiomi's plan. He knew the other man had his own calculations, but so did he. His original goal had always been to stop this Holy Grail War by 'severing' Irisviel.
But the situation now seemed a bit off. In his concealed state, all his senses were magnified in the quiet castle, which seemed to contain only the three of them. He could hear it. From the bedroom, just a door away, came Irisviel's shy whimpers, the sound of lips and teeth meeting, and the rustling of clothes being removed.
Soon, all the sounds were cut off by a soundproofing barrier. He couldn't hear anything from inside anymore. But by vaguely confirming the overlapping positions of the two people in the room through their mana, Kiritsugu, as an adult man, could still imagine what was happening inside.
"What is this?" A flicker of astonishment crossed his usually emotionless, machine-like eyes.
He had been an assassin for so many years, what hadn't he seen (×)?
This scene, he had truly never seen before (✓)!
He had encountered targets in bed during assassination missions before, but wasn't this combination a bit ridiculous? Did that evil little brat even have the ability? And... Irisviel looked so elegant and dignified, but was she secretly this kind of pervert?
Most importantly, Kiritsugu felt a strange emotion welling up in his heart. His chest felt tight. He didn't understand this feeling, but thinking about what was happening and what was about to happen just a wall away, he felt an inexplicable stuffiness in his chest. An unknown anger ignited in his heart. He even wanted to rush in and stop what was inevitably going to happen between the two people he wanted to kill.
"Why?" Kiritsugu frowned deeply, not understanding the source of this emotion he hadn't felt since he had killed Shirley and his father. He clearly didn't know this woman named Irisviel. And this development, though unexpected, was clearly advantageous for him. In the moment of ultimate ecstasy, a person's vigilance is at its lowest. That would be the best opportunity for him to assassinate her.
"Whatever." Kiritsugu's gaze became indifferent again. He carefully sensed the changes in mana, analyzing the state of the two people behind the door, searching for the perfect moment. But as time went on, he noticed something was wrong. Wasn't that little brat's stamina a bit too strong?
Their mana signatures chased each other around the room. The fragile door, now against the wall, creaked and shook continuously. Even without sound, Kiritsugu could further confirm that what was happening inside was indeed what he had imagined. The last shred of doubt in his heart vanished. For some reason, a wave of nameless rage surged through him. He suddenly wanted to switch targets and tear that monster to shreds.
At the same time, inside the room, Lin Jiuan, who was in the middle of his all-out output, paused. His gaze shifted from Irisviel's snow-white body to the wall she was leaning against. It wasn't in vain that I led her all over the room. I've found you, Kiritsugu Emiya!
Though it was only for an instant, he, who had been using one part of his mind to sense his surroundings, had detected the momentary flash of rage from Kiritsugu. However, he didn't immediately make a move on him. Instead, he attacked the target before him even more fiercely. In an instant, his output efficiency was maxed out. Dense and powerful attacks rained down on her like a torrential storm.
"Ehh? Wh-Why?" Irisviel moaned, her tone somewhat aggrieved. She had a feeling that Lin Jiuan's heart wasn't in it, and he was being too rough.
"Don't you like it?" Lin Jiuan slapped the rear taillight of the top-tier luxury car manufactured by the famous magus family, the Einzberns.
"Mmm, I hate it. Jiuan, you've suddenly become so hateful. It hurts," Irisviel said, tears in her eyes, her tone pitiful and wronged.
"Then bear with it."
"Ooh, Jiuan, I hate you, ooh... I never realized you were so bad before. I hate you so much."
Seeing the door shaking continuously, as if it would be knocked down by the force from behind it at any moment, Kiritsugu could no longer maintain his indifferent expression. A hint of anger appeared in his eyes. He was hard! His fists were hard!
