"Ahhhhhh

Illya, who lazily threw her body on the bed, sighed with pleasure on her face.

'Goo'~

However, as soon as she finished speaking, a strange voice sounded out of place.

"Illya, are you hungry?"

Miyu, who sat down on the bed gently, asked suspiciously. Hearing this, Illya turned around, lay on the bed and faced the ceiling with a smile.

"Ahh I do think I'm a little hungry. 」

"Wait patiently, my brother has already made dinner. 」

"Hmm!"

Illya, who was smiling and nodding her head, suddenly fell silent, not knowing what she was thinking.

"Illya?"

"Na~ Miyu. 」

Illya, who was a little distressed, frowned.

"Do you have time to go out together tonight?"

Hearing Illya's words, Miyu immediately figured out the overtone of Illya's words.

"Well, whatever Illya wants to do, I'll help you. 」

"Thank you, Miyu!"

Illya, who smiled happily, thanked her.

"Is that what you said about this afternoon?"

"Hmm. 」

Illya had no intention of hiding it, and directly stated the reason and purpose.

"Sure enough, after that morning, I always felt... I should do something. 」

"Do something?"

"Yes, that man named Mii Yuuki did not hesitate to seriously injure others for the sake of his sister. No matter how you think about such a person, it is difficult to conclude that he is completely evil. 」

「？」

Miyu, who didn't understand what Illya meant by saying these suddenly, glanced at the sapphire beside her suspiciously.

"Really, what the hell do you want to say Illya~"

Ruby from the warm quilt asked, pointing at Illya.

"Actually, it's nothing, I just thought. This morning he himself and we, will it also be for his sister... Something. 」

"Uh-huh...... It's not out of the question. 」

Ruby, who crossed her sides together like crossed arms, murmured.

"That's right, Ruby!"

Illya, who was affirmed, said a little excitedly.

"So, Lady Illya is planning to ...... tonight?"

"I want to see him one more time. 」

"Mmmm

Illya, who sat up suddenly, knocked Ruby to the side and turned to Miyu and Sapphire.

"Conveying us, no, conveying the heart of Sister Motoka Mikai. Just as he was angry at his sister's injury, his sister was crying silently because of his bruises. Make sure that guy is aware of this, even if it's a fight!"

"Oh~ I made up my mind to fight for the girl named Motoka Mii. 」

Ruby Road that staggered back.

"It's so good, it feels like it's burning. It would be nice if we could add a blood-pumping image of Illya's transformation. 」

"Rejected!"

Illya, who crossed her hands and made an 'X' to reject Ruby's proposal, suddenly thought of something, and turned to Miyu, who was also sitting on the bed, and asked.

"Come with me. 」

"Of course. 」

Hearing this, Meiyou agreed without any hesitation and smiled back.

"Because we're friends. 」

After being stunned for a while, Illya smiled happily after reacting.

"Well, we're friends!"

"No!"

As soon as Illya's words fell, a voice suddenly came from the door, and Illya, who was a little unwilling, asked rhetorically.

"Why, brother?!"

Hearing Illya's inquiry, Emiya Shirou just shook his head again.

"That guy wasn't just a few words to stop him. For the sake of his sister, he did not hesitate to attack so many children in the 'Garden of Hope', so he must have made a corresponding enlightenment. Tonight, a pitched battle is inevitable. 」

"In that case, I can fight, and I want to do something. 」

Not only Illya, but Miyu also expressed her thoughts. I saw her bow her head slightly to Shirou and pleaded.

"Please, I want to help my friends and Illya. 」

Seeing the firm appearance of the two of them, Shirou was also a little hesitant in his heart.

However, more than five months ago, during the Fifth Holy Grail War, Berserker was defeated and Illya was killed. and Mii Yuuki's surprise attack on the 'Garden of Hope' this morning, and the battle with Mikoto Misaka and Kaede Stars. It's all flashing back in time in my mind.

"Illya... Meiyou..."

Gently walking up to them, Shirou gently stroked their little heads and said softly.

"Just as Yuuki Mii did not hesitate to hurt others for his sister, I don't want my sister to be hurt in any way. 」

"Brother..."

"It's okay, leave it all to me. I'm going to make that guy come to his senses, isn't that what a 'righteous buddy' should do." 」

—————— Dividing Line——————

"Repaired. 」

In an unknown research institute, Mii Yuuki, who had fallen into a coma due to serious injuries, finally woke up.

"I'm here... Uhhh

Sitting up with a slight difficulty, Yuuki Mii glanced around suspiciously.

"This is...?"

"It's just a mediocre-looking institute. 」

The west wind and the blazing sun beside him curled the corners of his mouth.

"It's enough for you to know that you're still alive. 」

"yes, I failed. 」

My mind gradually recalls the battle with the third place in the school city not long ago.,And the last thing that appeared.,The target that he didn't hesitate to attack the children had to find.。

"What the hell is that? Is it the one who has the spatial ability to replace the weapon from a predetermined position to the person next to him? But in that case, where did those weapons come from, and what is the ultimate weight and distance of the replacement object?"

Yuuki Mikai, who was thinking in distress, couldn't help but punch himself in the head.

"Damn! I don't know much information!"

"Don't think about it, it's not that simple. 」

The west wind and the sun turned around, sat on a chair not far away, and assumed a relatively comfortable position.

"We've given you a simple treat, and at least with the help of the able, you don't have a wound on your body right now. But after all, you were directly stabbed into a hedgehog.,Such a serious injury,Even this technologically advanced school city,,Can't let you heal in a short time.。 」

"That's enough. 」

Yuuki Mikai, who put on his clothes and checked his physical condition, asked.

"You haven't forgotten the promise between us, have you?"

"Of course. 」

The west wind and the scorching sun swear by the way.

"Your sister has been treated by the school city for a long time.,That level of injury.,It's almost hopeless in the outside world.。 But if you rely on the most advanced technology in this school city, there is a possibility of treatment. And in proportion to this advanced technology drug, it is a matter of personal economy. I'll take care of that, and on the condition that you have to help me finish out that man, that's the agreement between us. 」

"Well, I'll keep my promise, so ......."

"Don't worry, I'm not going to backtrack, but on your side, will your sister still be able to hold on?"

「！」

The words of the west wind and the scorching sun made Mii Yuki instantly stagnate. As if waiting for this moment, the west wind and the scorching sun, with the corners of his mouth slightly raised, took out a small matchbox-sized box from his body and handed it to him.

The size of Mii Yuuki, who took the thing, was a small one or two unknown crystals inside.

"What is this?"

"It's called a body crystal, and it's said to be something that can enhance your abilities for a short time by making your superpowers run wild. 」

After finishing speaking, the west wind and the sun got up and patted Mii Yuuki on the shoulder.

"For the sake of your sister, you should work hard. 」

The crisp footsteps gradually faded away, and in the silent research institute, only Mii Yuuki stood there alone, silently staring at the "body crystal" in his hand.

"Motoka..."
