Tomioka Giyuu

Giyu is a tall young man with long, tangled black hair tied in a low ponytail. He has thin eyebrows and sharp dark blue eyes.

Giyu wears the standard black Demon Slayer uniform along with a haori featuring two different patterns: one solid red and one with a geometric pattern of green, orange, and yellow (which are based on the haoris worn by his deceased older sister and Sabito, respectively).

Butterfly Mansion is the estate of Shinobu and Kanae Kocho.

Story
At the estate, demon hunters can receive medical care or rest. Remarkably, hunters can remain at the estate until they are fully recovered.

However, most likely, only pillars or other hunters who have received an invitation to this place can receive help in this place.

After recovery, recovery training is carried out.
