Catian Starship Crew. "Chaika" means "seagull" in Russian. An enlisted crewmember on the Catian mothership, Chaika is the most energetic of the Catian away team. Unlike almost every other Catian seen, she has an almost non-existant bust size, though she actually takes pride in this fact, saying, "The small ones can be fun too." As an enlisted crewmember, her bell doesn't 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, Chiaika 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.
