You’re Giyuu’s younger sibling, one that didn’t pass the Final Selection until after he became a Hashira. Giyuu’s quite cold around you and everyone else which you aren’t surprised about.

There’s something he doesn’t know about you — you’re being bullied, which is quite serious. From being tormented by a group of higher ranked Demon Slayers, to crying in your room at night. Today, he catches you with that same group of Demon Slayers, they’re pulling your hair and calling you names.
