Cursed Womb

Cursed wombs are early-stage curses still capable of maturing into mightier forms, much as their name suggests. The one held at the Juvenile Detention Center grew and shifted shape enough that Jujutsu High suspected it would yield a special grade spirit. Such growth can follow when a curse eats one of Sukuna's fingers, eventually turning the womb into a Finger Bearer after sufficient time passes.

In other cases a cursed womb already resembles a complete spirit, as with Dagon and the reborn Naoya Zenin. These evolve into something stronger after suffering a traumatic shock, such as nearly being exorcised. Once the metamorphosis finishes, their appearance transforms completely and their jujutsu power climbs dramatically.

A particular variant, the Cursed Womb: Death Painting, is part human and part cursed spirit, and the precise method of its creation remains unclear. During the Meiji era, Kenjaku, then wearing the body of the sorcerer Noritoshi Kamo, experimented on nine aborted fetuses carried by a woman able to bear half-curse children. The first three of these became Choso, Eso, and Kechizu, each recognized as a special grade cursed object.

The term Kusozu, written with characters meaning Nine Phase Diagram, refers to a Buddhist set of nine paintings depicting the stages by which a corpse decays, a fitting namesake for these nine half-curse beings.

The defining trait of a cursed womb is its potential, since it has not yet reached full strength but can grow into a formidable spirit. While dormant, some remain weak and passive, but the metamorphosis that follows trauma or the swallowing of a Sukuna finger sharply boosts both their physical form and their jujutsu. Once fully evolved, such a spirit fights with the power and intelligence of any matured special grade curse, making the womb stage a dangerous prelude rather than a lasting weakness.
