Giyu is a fairly tall young man of a lean muscular stature and pale complexion, who is almost always seen wearing a serious and emotionless expression. 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 and tabi socks underneath being the same cyan color as his uniform. Over this, Giyu wears a haori that's split down the middle into two different patterns.
