Sakura Igawa (井河 さくら) is the younger sister of Asagi and one of the main characters of the series. Starting out as a trainee Taimanin in TA1, she became a full-blown Taimanin in TA2, going on missions with her sister. Later in the timeline, she becomes a teacher at Gosha Academy, as shown in Taimanin Yukikaze and Taimanin Asagi 3. In the Action Taimanin timeline, she is still a student, with the age gap between her and Asagi being much wider.
