Kage

Kage (カゲ) is a former member of the Kage Assassin Clan and now Prince Bojji's friend.

Plot
Kage is a former member of the Kage Assassin Clan that was nearly annihilated. Renouncing his former assassin ways, he turned to thievery to survive. Since meeting Prince Bojji, the two go on many an adventure in a coming of age sort of tale involving the two.

Like Bojji, Kage is also a cursed being, however his curse seems to be a hereditary one given to every member of his clan, supposedly as a divine punishment for some ancient offense they committed against the gods. This seems to give him a mild resistance to certain curses, as his pre-existing curse refuses to be replaced by anything else.
