Kim Si-Hyeon

Si-Hyeon Kim is the deuteragonist of the series. He is a high-ranking Korean hunter and the guild master of the Seoul guild. He was with Hyeon-U Kim back in 2006, as they were both first-generation hunters that cleared the tower. However, he was significantly younger at that time.

Hyeon-U remained his best friend and currently lives at his place, since he no longer has a home.
