Birdy the Mighty: Decode (2008) : 1x2

Birdy and Tsutomu try to cope with existing by sharing one body, but leading two separate lives. Birdy's commanding officer, Magius, informs Tsutomu that his original body's being restored and it will be some time before he can live outside of Birdy's body. Bacillus tries to eliminate Birdy by luring her into a movie shooting as cover. Keisuke Muroto tries to take photos of Bacillus and Birdy, but falls unconscious when he was knocked out by debris. A wounded Bacillus took over Geegar's Earth body as his first one was damaged from deterioration and from fighting Birdy.
