Despite Minna's objection, Mio heads inside the Yamato and gives the Neuroi Dynamo her remaining magic power, allowing the cannons to be fired, which destroys the Neuroi nest. It is not enough, however, as the Neuroi somehow regenerates, trapping Mio in its massive core, and using her shield. Not giving up, Yoshika, with backup from the other Witches, retrieves the Reppumaru and destroys the giant Neuroi core with a Reppuzan that drained all of her magic power, freeing Mio in the process. With Venezia finally free from the Neuroi, the 501st Strike Witches are once again formally disbanded; and Yoshika begins her medical career.
