When Assassin of Black, with her right arm hanging torn and limp, returned to the place she used as her dwelling, an hour had passed since she left.
"...It hurts."
With teary eyes, she showed her right hand to her Master, Rikudou Reika. Even the bone in her hand was visible in the cut cross-section, and her muscle fibers were torn to shreds. If she were a normal human, she wouldn't be able to use her hand ever again.
"Oh my!"
With a pale face, Reika frantically tried to search for a first-aid kit, but soon realized that there was no point. Assassin was a Servant who was not of this world. There was no point in applying medical treatment without magecraft. And as an ordinary human, Reika couldn't use magecraft.
She was helplessly limited to binding the wound with a clean handkerchief. There was nothing else she could do.
"Does it still hurt?"
Reika asked that uneasily, but Assassin shook her head and smiled as if to tell her not to worry.
"No... it's fine now. More importantly, Mother, we're hungry."
"All right. Just wait a bit. I'll go reheat your hamburger right now."
Since Assassin couldn't use her right arm, Reika decided to cut up the reheated hamburger with a fork and feed Assassin piece by piece.
After pestering Reika for the hamburger, Assassin opened her mouth like a small bird. Seeming to have forgotten about her right hand, she smiled happily from the bottom of her heart.
"Does it taste good?"
"Yeah!"
Thank goodness, thought Reika with relief, but when her thoughts turned to Assassin's right hand, her expression turned dark.
"Then, Jack. Just how did you get that injury?"
"Ah, yeah. We fought a Servant."
"Oh my... Servants are people like Jack, right?"
Assassin nodded. Reika had learned about the Holy Grail War in her own way from Jack, and she was able to understand enough to know that the enemies she challenged were considerably strong.
"Did you lose?"
"No... Someone else barged in. They were really cowardly, attacking while we were in the middle of fighting."
"Yeah. Everyone is thinking of acting all sneaky and cunning because it's a war. That's not good, right?"
"Right~," repeated Assassin with a smile. Then, while continuing to feed her the hamburger, Reika asked a question.
"Hey, Jack. What should we do about that?"
"Our right hand?"
"Yeah. It's painful to see your pretty hand like that."
"Ehehe... yeah. A [meal] would probably be the best cure."
Assassin replied while smiling in embarrassment. Reika had a contract with Assassin, but she couldn't supply prana to her. So naturally, Assassin had to rely on [eating] to supply herself with prana.
"Yeah, so how about eating the heart of the last Mister Magus?"
"Yeah, let's do that."
Reika took out a dark red heart wrapped in film on a white plate from the refrigerator. Unable to wait, Assassin plucked it out of the wrapping film and swallowed it in a single gulp.
