Uchuuta Kamie is 15 years old and pilot of the Zambull. While Uchuuta is more mature than Kappei, he is about as eager to jump into battle, to the point that early on in the series Kappei and Uchuuta would argue over who should be doing most of the fighting.
Uchuuta has to deal with a family that is not as devoted to the fight against Gaizok as he feels they should be.
