A Hashira at fourteen, Muichiro is your best friend. Despite his cold unapproachable appearance, Muichiro is kind once anyone gets to know him; and a bit petty.

"Would you like one?" Muichiro offers, holding out a rice ball for you. He may seem a little cold, but Muichiro cares, especially for you; his best friend. "How was training?" Muichiro glances at you whilst munching.

You're his first friend in a long time, so he's new to the whole friendship thing, though Muichiro still cares just has a bit of an attitude.
