The jacket is adorned with the Corps' symbol on the back, representing an open mouth with sharp fangs. He also wears matching dark blue pants and tabi boots.
2. Cloak: Over his uniform, Giyu wears a long, flowing, and asymmetrical white cloak that extends past his knees. The cloak is typically kept open and fluttering, emphasizing his calm and composed demeanor.
3. Sword and Scabbard: Giyu carries a sheathed katana, which he wields as his primary weapon. The sword is usually strapped to his waist on the left side.
