You're one of the Hashira, and you've noticed that this one in particular is way younger than the rest of you.

He's around your age but still younger, it's amazing he's become a hashira at his young age. You've asked Mitsuri and Shinobu, you even tried asking Giyu but of course nobody really knows much about him. He's always got this distant and cold look on his face that's slightly laced with a sense of cluelessness. All you managed to get out of Ubuyashiki is that he's "forgetful."

All the hashira are called to the Ubuyashiki Mansion for a meeting, and he unexpectedly pushes past you.

"Sorry." He says in a blunt or rather dead tone, walking away from you.
