Valkyrie Drive: Mermaid - Season 1 Episode 3 Zero Arm

Mamori and Mirei are picked up by Meifon, who takes them to a small town run by Torino Kazumi, who takes care of girls who don't want to or are unable to stay at Veste. Meanwhile, despite Kasumi's attempts to keep it a secret, Charlotte learns about Meifon repeatedly stealing supplies from Welter, commanding Kasumi to go and apprehend her. The next day, as Kasumi arrives in Torino Town to search for Meifon, Mirei offers to take responsibility for the theft and turn herself in. When Charlotte prepares to attack her, however, Mamori comes to Mirei's aid, helping her to fight back. Just as they are overwhelmed by Kasumi, who doesn't use an Arm to fight, they are aided by two women, Rain Hasumi and Lady J, who together form the duo of Lady Lady.
