Klahadore is actually the dread Captain Kuro. Having lost his love for all things pirate, he travels in disguise as part of an evil plan to make Kaya very, very sleepy - and steal all her money!
Jango is a handy when it comes to putting people in trances and a key part of Kuro's money grubbing scheme. You have to watch him, though. He has a tendency to hypnotize himself, at which point he just might moonwalk the plank.
