Chaika

チャイカ

Catian Starship Crew.
Chaika is an enlisted crewmember on the Catian mothership and the most energetic member of the Catian away team. Unlike nearly every other Catian seen, she has an almost non-existent bust size, though she actually takes pride in this fact, saying, "The small ones can be fun too."
As an enlisted crewmember, her bell does not allow her to change clothes instantly, a fact she complains about to the others. When Aoi and Manami want to train with cooking and firearms respectively, Chaika shows them to the mothership's simulation room to allow them to do so without bothering the neighbors.
Her favorite task is Embassy duty, since she can just lounge around and eat snacks all day.
