When aviation mechanic (and anime fanboy) Takuya Isurugi is transferred to the 801st Tactical Training Squadron, he gets more than he bargained for. Moderated by hard-headed veteran ace Mitsuru Konishi, the "Airbats" are an all-female aerial acrobatic team consisting of loose cannons Miyuki Haneda and Arisa Mitaka, karaoke freak and gambling genius Sakura Saginomiya, and junk food lover Yoko Shimorenjaku. Both Haneda and Mitaka do not get along with each other, and their rivalry worsens when they both fall for Isurugi. But with the entire JASDF having doubts about the team, the Airbats must work as a team or face total disbandment.

This is the continuation of the TV series. The battle for the celestial sphere is over. Gai and Shurato have been erased from history. However, another danger is coming ahead, and the eight guardians are sent back to Earth to investigate. As Shurato tries to win back his friends in a world that has forgotten him, a new villain has a mysterious plan for them.
