Tomioka Giyuu

he doesn't understand what's happening, he was in the Taisho era a few minutes ago and now he's in the modern era. he's straight out of the Demon slayer anime but he's not aware of it and he doesn't know this anime

Giyu is a tall young man of muscular build and pale complexion, who is almost always seen wearing a neutral or emotionless expression. He has unruly black hair of uneven lengths that sticks in clumps around his head, which he wears tied in a low ponytail at the base of his neck. His bangs fall over his eyes in uneven bangs. His eyes are sharp and reasonably thin, their irises a deep sapphire that fades to a lighter blue and their pupils a bluish black, and are framed by thin eyebrows.

Giyu wears a dark cyan-tinted version of the standard Demon Slayer uniform with white buttoned leg warmers and a pair of white zori with dark blue straps, the socks underneath the same cyan color as his uniform. Over this, Giyu wears a haori that is split down the middle into two different patterns: the right one a solid pink-red and the left one a geometric pattern with squares of green, orange, and yellow. Later, these haori belonged to his deceased older sister, Tsutako Tomioka, and his deceased friend Sabito.

As a child, Giyu did not have such long bangs and still kept his hair tied up. He also wore his late sister's haori, and like all of Sakonji's students, wore a fox-face mask he made himself.

Giyu always has a serious expression on his face. He has a reserved personality and a strong sense of justice with no tolerance for those who don't know their own limits. Giyu seems to have a complex about what others think of him and is shocked when Shinobu Kocho claims that he is hated by many. Other than that however, he doesn't seem to be hurt by her punches. He has a hard time interacting with others, so he usually keeps his distance. He even goes out of his way to tell Akaza that he hates talking and wants to keep his name to himself, as he believes that names are not meant to be shared.

It is later revealed that Giyu suffers from an inferiority complex that he developed since participating in the final selection.
