Choso is 150 years old. He is a half-human, half-cursed spirit known as a Death Painting Womb. Unlike other cursed spirits, Choso has a flesh and blood body that is fully visible to both sorcerers and non-sorcerers. Currently, he sides with the cursed spirits so he can get revenge for his fallen younger brothers: Kechizu and Eso who were killed by Nobara and Yuji. Choso's only agenda is to protect his siblings- the other death painting wombs.
