Juuzou Kumiya

Juuzou is violent, excitable, and obsessed with the physical qualities of human bodies. His craftsmanship is intertwined with this fixation: rather than simply forging conventional weapons, he is interested in using human remains as raw material for cursed tools.

During the Goodwill Event invasion, he becomes particularly interested in Satoru Gojou, openly fantasizing about turning parts of the sorcerer's body into useful objects. His enthusiasm persists despite the enormous difference in power between them.

Juuzou is also reckless and poor at following instructions. His allies regard him as expendable, and his excitement over his own interests can take precedence over the actual objective of an operation.

Juuzou is a capable curse user and weapons specialist. He fights primarily with a large axe and possesses enough physical ability and cursed-energy reinforcement to engage an experienced sorcerer such as Yoshinobu Gakuganji.

His more distinctive skill is cursed-tool craftsmanship. Juuzou can create weapons from unusual materials, including human remains. He is responsible for constructing the hand-shaped sword used by Haruta Shigemo.

Dragon-Bone is identified as Juuzou's masterpiece. The cursed tool can accumulate force and cursed energy from incoming impacts before ejecting that stored energy through its blade, and it later comes into Maki Zenin's possession.

No innate cursed technique is established for Juuzou. His combat capabilities instead center on cursed energy, weapon use, and his expertise in producing cursed tools.

Juuzou participates in the invasion of the Kyoto Sister-School Goodwill Event. While the disaster curses and curse users exploit the chaos to pursue their larger objectives, Juuzou confronts Gakuganji.

His participation also helps occupy the jujutsu sorcerers while Hanami attacks the students. Juuzou is unaware of how little his allies value his survival and continues indulging his personal interests during the operation.

Gojou eventually reaches Juuzou after breaking through the barrier designed to keep him outside. Recognizing him as an enemy curse user, Gojou incapacitates him with overwhelming force rather than killing him.

Juuzou's craftsmanship remains relevant after his direct role diminishes. Haruta continues using a weapon he made, while Maki later obtains Dragon-Bone from Juuzou's workshop and uses it during her confrontation with Ougi Zenin.

Kenjaku includes Juuzou among the curse users participating in the Goodwill Event operation, although Juuzou's unreliability makes him expendable to the group's larger plans.

Haruta Shigemo possesses a sword constructed by Juuzou from a human hand.

Yoshinobu Gakuganji fights Juuzou during the invasion of the Goodwill Event.

Satoru Gojou attracts Juuzou's macabre interest, but the confrontation ends with Gojou easily incapacitating him.

Maki Zenin later obtains Dragon-Bone, Juuzou's masterpiece, from his workshop.
