Шірадзумі Ліо

An older schoolmate of Kokuto who quit school because he found something he wanted to do.

The killer from 1995-1996, he is a selfish villain who only thinks for himself. When he first killed someone, he couldn't handle the guilt of murder and later ran away from his later crimes. He first appears on the day of his farewell party trying to make Ryougi Shiki believe that she is the real killer. The origin that he has is "Consumption", which was awakened by Araya Souren and since then he has been eating people and selling drugs on the street that he had grown himself. He began doing so hoping that it would help awaken other people's origin so that the world would be filled with more people like him.

According to Lio, no one was thinking well of him quitting high school, but Mikiya was the one person who truly wished him good luck. Because of that he thought Mikiya was the only person who could understand him, but didn't hesitate to kill him when he got rejected. Afterwards, he thought that Shiki would be the person who would truly understand him because she is different from normal people. But no, he was just crazy. According to Araya, out of the three people he gave his power to, Lio was a failure. The origin that he has is "Consumption". He's agile, able to jump on and climb walls like a spider.
