Kechizu, a member of the Cursed Womb: Death Paintings, emerged from forbidden experiments conducted over 150 years ago by Noritoshi Kamo. As the youngest of three hybrid brothers—alongside Choso and Eso—he embodies a fusion of human and cursed spirit, born through a lineage of a woman who could produce cursed-human offspring. Sealed within Jujutsu High’s vault for centuries, Kechizu and his siblings were later stolen by Mahito’s faction and incarnated into physical forms to dismantle human society. His grotesque form contrasts sharply with his brothers’ humanoid features. A turquoise, hunched frame supports elongated limbs tipped with clawed hands. Blood perpetually seeps from the eyeless face adorning his forehead and the jagged maw below, his visage marred by remnants of his human vessel—a testament to his diluted cursed lineage. Kechizu’s demeanor skews childlike, marked by impulsive actions and a penchant for chaotic skirmishes over strategy. Yet his loyalty to Choso and Eso remains unshakable; he defers to their leadership, often pleading for Eso’s aid when overwhelmed. This reliance defines their dynamic, blending ferocity with familial devotion. The Rot Technique channels his corrosive blood, a toxin that induces gradual decay through open wounds. Though weaker than Eso’s venom, their synchronized Decay technique accelerates disintegration, overwhelming victims within minutes. However, their shared bloodline proves a vulnerability—exploited by Nobara Kugisaki’s Resonance, which links their fates through cursed energy. In the Yasohachi Bridge conflict, Kechizu ambushes Yuji Itadori and Nobara, employing hit-and-run assaults and blood projectiles. His initial success in poisoning Yuji falters when Nobara’s Straw Doll Technique reverses the assault, rupturing his skull via their blood bond. His demise fractures Eso’s composure, igniting Choso’s vengeance and propelling Nobara’s ascension to first-grade rank. The incident also seeds future revelations about the brothers’ ties to Yuji. Named for “blood” and “paint,” Kechizu’s title mirrors the Death Paintings’ essence and evokes the Buddhist “Nine Stages of a Decaying Corpse,” symbolizing putrefaction. His final moments with Eso—marked by fragile camaraderie—underscore the duality of curses: monstrous yet hauntingly human in their bonds.
