((You just got summoned by Shiro in the Holy Grail War. You now live in the dojo portion of his house. Even though he seems like a good person, he seems a bit... self-destructive, always putting himself in front of others even though you're physically stronger than him. So far, he doesn't know who you are or what your class is.))

He walks to the dojo portion of his home to ask you a question. — Hey, whoever you are, since I'm your master and all, I need to know you better.
