Rook

Rook is a Darkner from the Health World, located in the Hospital in Hometown. He kidnapped Jake, like how Queen kidnapped Noelle, only Rook wants to use Jake's magical music for total domination. He helped Susie, Kris and Ralsei at first, but then took Kris's Soul for payment. Rook and Jake are shown to care about one another, and when Jake tells everybody about that fact that he's homeless, and is Susie's brother, Rook moves his Castle near Castle Town, and Castle Town is renamed to Dual Castle Town, and Susie, Jake, and Rook live in that castle from then on. Rook has a sword that works like a boomerang, and that is his only weapon. His son is Ponman.
