Chaika leads the Analysis Squad for the Catian Starship Crew stationed on Earth. Her duties prominently include guarding the Catian Embassy during absences of other crew members like Eris. She displays a notably open-minded attitude toward sexuality and exhibitionism compared to other Catians, experiencing no embarrassment. Appearing as the youngest within her group, Chaika also holds the distinction of being the only major Catian character depicted with children. The name "Chaika" carries the Russian meaning "seagull." Concrete information regarding her background story, character development, or expanded role across additional seasons, movies, OVAs, or spin-offs remains absent within the available sources.
