Seiji Yagiri

Seiji Yagiri (矢霧 誠二,Yagiri Seiji) is a classmate of Mikado's. He quits school claiming he has something more important to do with his life, and later says that his goal is to find his 'true love' and run away with her. He is actually in love with Celty's head, which he first discovered when his sister, Namie snuck him into their uncle's study to look at the head. Seiji was being stalked by Mika Harima, until she broke into his apartment and discovered Celty's head, which he stole from his sister's research lab. Seiji then tried to kill her, and had his sister transplant Celty's head onto Mika's body. However, Seiji then finds out that he hadn't killed Mika, and that she had only gotten cosmetic surgery to look like Celty's head.
