Despite her efforts to heal Mio's grievous wound, Yoshika is confined to her quarters. With the other Witches doubting her story of the human-form Neuroi, Yoshika takes off by herself to find the truth.

The 501st Joint Fighter Wing is disbanded with the unveiling of the unmanned anti-Neuroi unit, Warlock. As the Witches scatter, something goes very wrong during the Warlock's sortie against the nearby Neuroi hive.

Yoshika launches alone against the out-of-control Warlock, desperately holding out as the other Witches race to join her and put an end to the monstrous hybrid of human and Neuroi technology.
