Birdy the Mighty: Decode

Space Federation officer Birdy Cephon Altera arrives on Earth in hot pursuit of the alien fugitive Geega, who has blended into human society through the fashion world. To get close to her target, Birdy adopts the identity “Shion Arita” and signs with a modeling agency—spending her days in photo shoots and industry events, then switching to nighttime hunts for interstellar criminals.

At the same time, ordinary high schooler Tsutomu Senkawa stumbles into an abandoned building with a friend, only to cross paths with Birdy’s showdown against Geega. When Tsutomu is taken hostage, Birdy’s attack goes tragically wrong and costs him his life. Unable to accept it, she preserves him by merging his consciousness with her own body.

Sharing one body forces Birdy and Tsutomu into an uneasy partnership, juggling his school life, Shion’s rising modeling career, and the escalating dangers of Birdy’s work as a Federation officer.
