Birdy the Mighty (鉄腕バーディー Tetsuwan Bādī?) is a manga by Masami Yuki, who is best known for producing the long-running series Patlabor. His initial work on the series was quickly abandoned, but it was made into an anime, which was produced and, on the last episode, scripted by Yoshiaki Kawajiri, who is known for anime titles such as Vampire Hunter D, and Ninja Scroll. The character designer and animation director for the series was Kumiko Takahashi. In 2003, Masami Yuki began serializing a second, more ambitious Birdy the Mighty manga in Weekly Young Sunday[1].

The second season titled Birdy the Mighty Decode 02 aired Jan 9, 2009 to Mar 27, 2009. The TV series featured a different seiyū cast from the original OVA series.[2] At Anime USA 2009, Funimation Entertainment announced that it had acquired the show.[3][4] As of June 30, 2010, Funimation released all episodes of Season 1 and Season 2 English Subbed, and plans to release them English Dubbed in October 2010.[5]


Birdy Cephon Altera is a Federation agent chasing interplanetary criminals to the planet Earth. While in pursuit of one such criminal, she accidentally kills a high school boy named Tsutomu Senkawa. Fortunately for Tsutomu, there is a way to keep him alive. He ends up being merged into Birdy's body and must remain so until the repair of his body is complete.

So, Tsutomu is stuck sharing a body with an attractive, strong, and impulsive space police agent while trying to keep his family and friends from finding out about Birdy. In the meantime, Birdy continues her investigation. Together, they take on a secretive group of evil aliens planning to perform experiments on the unsuspecting inhabitants of Earth.

Only one volume was ever collected[6]. In 2003, after a number of other series for Shōnen Sunday, Masami Yuki moved to Weekly Young Sunday, a seinen magazine, and began drawing a remake version, starting the story from the beginning.
