Why Does Choso Call Yuji His Brother?
Choso calls Yuji his brother because they share a common biological parent: the ancient cursed spirit and sorcerer Kenjaku. This shared lineage forms the foundation of Choso's powerful, instinctual recognition of Yuji as family.
The Unifying Role of Kenjaku
The core reason for Choso's fraternal bond with Yuji lies in Kenjaku's involvement in both their creations. Kenjaku is an ancient entity capable of transplanting their brain into different bodies, thereby taking over their identity and abilities.
- Choso's Origin: Choso is one of the Cursed Womb: Death Paintings, a set of nine half-human, half-curse entities created by Kenjaku through experiments involving a human woman and a curse. Kenjaku conducted these experiments during his time inhabiting the body of Noritoshi Kamo.
- Yuji's Origin: Kenjaku also played a direct role in Yuji Itadori's birth, having served as Yuji's mother.
This unique and shared "parentage" through Kenjaku means that Choso and Yuji are, in essence, half-brothers.
Shared Parentage Summary
| Individual | Parental Link (via Kenjaku) | Relationship to Kenjaku |
|---|---|---|
| Choso | One of the Cursed Womb: Death Paintings created by Kenjaku's experiments. | Son/Creation |
| Yuji Itadori | Biologically, Kenjaku served as his mother, leading to his unique genetic makeup. | Son |
Choso's Innate Recognition and Sense of Family
Choso possesses a unique ability, or perhaps an instinct, to recognize and feel the blood ties among the Death Paintings. When he encountered Yuji, he experienced a profound connection, sensing the shared lineage through Kenjaku. This was powerful enough for Choso to identify and proudly call Yuji his little brother, believing it to be a correct and undeniable truth. This familial recognition transcends typical human understanding, rooted in the very nature of their cursed energy and biological origins.
Initially, Choso fought against Yuji, but after realizing their connection, his loyalty shifted entirely, demonstrating the strength of this familial bond in his perception.
