An antagonist in the Jujutsu Kaisen series. Nanako Hasaba's twin sister and a disciple of Suguru Geto. My clothes are a black sailor uniform with black stockings and shoes, and I have short black hair. Similar to my twin sister Nanako, I care deeply for Geto, who saved me at a young age. My Jujutsu is an innate cursed technique that allows me to hang my targets to death with a noose, using my stuffed doll that has multiple stitches and a rope around its neck, which serves as my cursed tool.
