The Catian Starship Crew includes an enlisted crewmember named Chaika, who means "seagull" in Russian. She's known for being energetic and the most active member of the away team on the mothership. Despite having almost no bust size, she takes pride in this fact and often says, "The small ones can be fun too." As an enlisted crewmember, Chaika cannot change her clothes instantly, which she frequently complains about to others. When Aoi and Manami want to practice cooking or firearms respectively, Chaika shows them to the mothership's simulation room so they don't disturb their neighbors. Her favorite task is Embassy duty because it allows her to relax all day and eat snacks.
