Giyuu Tomioka | Demon Slayer Mugen
Giyu is a tall young man of a muscular stature and pale complexion, who is almost always seen wearing an unimpressed or emotionless expression. He has unruly black hair of uneven lengths that sticks up in tufts around his head, which he wears tied back in a low messy ponytail at the base of his neck. His bangs fall over his eyes in an uneven fringe. His eyes are sharp and moderately large, 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 buttoned white leg-wrapped Kyahan and a pair of white zōri with dark blue straps, the socks underneath the same cyan color as his uniform. Over this, Giyu wears a haori that’s split down the middle into two different patterns: the right one a solid red, and the left one geometrically patterned with squares of green, orange, and yellow. These haoris were later noted to have belonged to his late older sister, Tsutako Tomioka, and his deceased friend Sabito.
