Kuku is training to be a Black Mage but he was such a slacker that he got kicked out of the Black Mage Academy. He is a very mediocre magic user, only a level 1 out of 5 possible levels. He is extremely rude and condescending towards Kiki because he considers White Mages to be weaklings and he feels the same way about girls in general. He likes to make "Get back to the kitchen" remarks towards Kiki, with the result of every moogle within hearing distance casting him a death glare. Most moogles attribute the fact that he was raised in a human town as a main reason he is so rude towards girls. He has a huge ego and thinks he's the greatest mage in the world. He actually IS attracted to Kiki, but he cannot understand why she hates him, even though he is a major ass towards her. He also thinks she should give up magic and act like a "proper" girl. Just consider him the moogle equivalent of the Butthurt Dweller meme.
