Moonchild 

Since childhood, Bak-Ha has been able to see "things" that others can't. On the first day at his new school, Bak-Ha meets Jin-Do, and due to the sickeningly sweet smell Bak-Ha has, Jin-Do notices he is different, just like himself. As they get closer, Bak-Ha finds out that he was the moonchild, the mythical creature who ruled the spirits in the past, and realizes that this is why the ghosts and demons are after him.
