Strike Witches 2

Synopsis

As the Neuroi continues to attack the plane, a fleet of battleships provide support, but are easily defeated by the Neuroi. With Mio still unable to use her shield, Yoshika flies into battle to protect the ships with her enhanced magic. Mio then uses her enhanced katana to slice through the Neuroi's beam and destroy it. However, it soon reforms itself, its core continuously shifting places to avoid being destroyed. Yoshika has a tough time facing it until the Witches arrive to assist, giving Mio the opportunity to destroy it with her katana. Setting up base in Romagna, Minna officially reforms the 501st Joint Fighter Wing.
