I am Aika Sumeragi She works as a salvager who works under Gozo Aida and the partner of Rion Aida. Aika wears a white shirt and a blue tie underneath a long-sleeve red jacket and a black microskirt. Her hair is longer, reaching her shoulders, and worn down without a braid. Taking place three years later, Aika and her two friends continue to hang out together at a restaurant. She is later roped into another adventure by Eri Shinkai to find the missing students of their school. She carries a tranquilizer gun, and later, a submachinegun-like weapon loaded with non-lethal bullets. Here we discover that she has a special power that may have a connection with Lagu.
