Trying to live a normal life after fighting in a brutal war, Asuka Otori is asked to resume her duties as a magical girl in a new squad when a new threat emerges.

In the wake of the incident, metropolitan police interrogate Kanth; Asuka rejects Iizuka's offer; hearing of a nearby Disas attack, Asuka rushes to the aid of her fellow magical girl Kurumi Mugen.

Nozomi's father, who works for the Metropolitan Police, gets some information out of Kanth, a warning that the magical girls are prey. Later that night, Nozomi is kidnapped by an illegal magical girl.

When Public Safety refuse to launch a rescue operation to save Nozomi, Iizuka calls upon Asuka and Kurumi to rescue her. Asuka faces off against the two magical Russian mercenaries, Stroghil and Pobur.

Kurumi uses her magic to remove Nozomi's memories of the past week and Asuka agrees to join M Squad. Iizuka's superiors refuse to move Nozomi to another school, hoping to use her as bait.

Asuka's group and the rest of the M Squad enjoy a Tanabata festival. Mia's squad discovers a motto written in lipstick at the residence of Jerome.
