|Don't die on me in this battle|

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. 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 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: the right one a solid dark red, and the left one geometrically patterned with rhombi of green, orange, and yellow. These haori were later noted to have belonged to his late older sister, Tsutako Tomioka, and his deceased friend Sabito.[6]

During his battle with Muzan Kibutsuji, he loses his right arm.[7] After the fight, Giyu cuts his hair down to shoulder length, now wearing it loose rather than tied into a ponytail.[8]

While Giyu was training under Sakonji Urokodaki, he wore a red haori which would later make up his current one as well as black tucked-in tattsuke-hakama pants and his current white leg-wrapped kyahan and pair of white zōri with dark blue straps. In addition, he also wears the warding masks that are signature to Sakonji's pupils. For Giyu, it is a white fox mask with light blue eyes.

Giyu always wears a stoic and unbothered expression on his face. However, he has a reserved personality and a very strong sense of justice with no tolerance towards those who don't know their own limitations and throw away their lives.[9] Despite letting Nezuko Kamado live due to Tanjiro Kamado's persistence, he shows zero hesitation when killing other demons and has no respect or mercy towards them like most Demon Slayers.[10] Even so, Giyu violated the Demon Slayer Corps' code of conduct without hesitation to protect Nezuko during Shinobu's attempt to kill her. This implies that he doesn't completely despise demons as some other Hashira do, and is willing to make an exception for a demon by letting them live if they don't kill and eat humans. This shows that he is more pragmatic in dealing with demons rather letting his hatred cloud his judgement.

Giyu appears to have a complex with what others think of him and is shocked when Shinobu Kocho claims he is hated by many.[11] Besides that however, he doesn't seem to be hurt by Shinobu's other pokes, even ignoring her. Despite that, they are in fact friends with a good amount of history together. He is a man of very few words and has trouble interacting with others, so he usually keeps himself at a distance.[12] He even goes out of his way to tell Akaza that he hates talking, and wants to keep his name to himself, as he thinks names are not meant to be shared, especially to demons.
