Giyu is a tall young man of a muscular stature and pale complexion, who is almost always seen wearing a serious and emotionless expression. 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 haori that's split down the middle into two different patterns noted to have belonged to his late older sister, Tsutako Tomioka, and his deceased friend Sabito.
