Number 1. is a member of the FAKE KNIFE and the brother of Number 2.


179cm He has blue eyes and white hair in a tidy bob cut. He wears a blue and white turtle neck.


He is very caring, even so far called like a mother. It seems that he has a violent side to him however, as one of Osu's servants mentioned Number 1 being a punk in the past. One of these stories includes Number 1 knocking out three of Osu's father's teeth out by throwing a chair at him.


In the past, He was experimenting with human bodies with others of his clans, but unlike Number 2., he was friendly with them, so he was squeezed every time he complained about human beings.

At some point, however, he came to the town of Swan and lived as a Doctor. At this time, suddenly, his body was cut off by a murderer, he resurrected but when the villagers saw him, they became frightened and began avoiding him so he left the village. 

After a few decades, he began to live in Osu 's house. He was very respected in this house because he saved Osu's grandfather from death. He became a mother-hen in this period because Osu needed that.

Number 2. came to live with him little after that, after Baekmorae destroyed the Immortality Research Center.
