What's the deal with Kai's name?
Everyone else fits a scheme.
Roca Rourin (Rock n' Rollin')
Poko (the sound tanuki makes when they beat on their belly) Rakun (Raccoon)
Momo (Pink, wears a pink dress) Otako (Tako, octopus, play on otaku)
Coni Confetti (Coni like Coney island which has a clown for it's logo.)
Kai Saikota ???? (Edit: I guess since she's supposed to be a god, Saiko could be alluding to that)
