When a criminal group connected to the Ryunka incident escape from custody, hiding themselves and their alien identities on Earth, Birdy and Tsutomu are thrown back into action. It seems, however, that there are other forces involved, as well as old faces, which give Birdy time to reflect on the past, and the people that influenced her. (Source: Anime News Network)
