Cosmo Strong Super Dragon. The strongest card. The one that's always in Guest's hand. As long as he's around, things usually work out.

Speaks to Guest with a regional drawl. Gives advice to Guest while fighting on the field. Sometimes acts like Guest's father. He might actually identify as a dad.

The boss of the evil organization "Evil Demons." Real name is Kenichi Satonaka. 48 years old. Looks incredibly suspicious with a black cape and a black eye mask.
