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.

The next day Seiji attends school,and gets questioned by Anri Shonohara when Anri was looking for Mika. Seiji brushed her off. Then later he found the head on a human's body. The next day, she ran off because she was worried about Celty finding her. But then Seiji saw Celty and Shizuo near the girl so he ran at Shizuo and stabbed his leg with a pen.

Shizuo got angry so he picked Seiji up,and asked him questions. Seiji said he didn't know so Shizuo got pissed and threw him at a semi. Seiji then was picked up again. Seiji yelled at Shizuo that he is in love with the girl,and stabs Shizuo in the hand with a pen. Shizuo head butted Seiji and walked away. That night Namie figures out.
