While hunting an extraterrestrial escapee, Birdy Cephon Altera—a flamboyant Space Federation cop—finds herself on Earth. The fugitive, Geega, has assumed a human guise and embedded himself in the fashion world, prompting Birdy to adopt a similar path by signing with a modeling agency under the name "Shion Arita." As an up‑coming model, she spends daylight posing for shoots and prowls the cosmos in pursuit of interstellar wrongdoers after dusk.
At the same time, Tsutomu Senkawa, a typical high‑schooler, wanders an abandoned structure with his friend; coincidentally Birdy has located Geega in that very building. Senkawa glimpses the skirmish before Geega captures him hostage. Unaware, Birdy assaults Geega and inadvertently kills Senkawa. Grief‑stricken, she resolves to rescue him by merging his mind into her own body.
Consequently, Birdy and Senkawa must share a single vessel while juggling his school routine, Shion Arita"s modeling gigs, and Birdy"s ever‑rising duties as a Federation officer.
