Harima Mika

Mika is a friend of Anri Sonohara, who had been looking for her after she had disappeared from her home. She was a stalker, and had been stalking Seiji Yagiri until he accidentally "killed" her. Seiji then asked his sister to transplant the head of Celty onto Mika. However, Namie, Seiji's sister, merely gave her cosmetic surgery to look like Celty's head.
