Federation investigator Birdy chases the space criminal Geega through space to Earth, where he hides in the entertainment industry under a human disguise. Birdy goes undercover herself, posing as famous model âArita Shionâ that often uses a âspace girlâ look. A male student, Senkawa, stumbles upon a fight between the two one night in an abandoned building only to be severed in half as he is used as a shield by Geega against Birdy. Birdy heals him from imminent death in some fashion- but Senkawas body, and life, are now changed and permanently linked to Birdy.
