Frame Arms Girl Episode 12

Spurred on by Ao's wish to help Hresvelgr, the other F.A. Girls send all of their weapons to Gourai to help her fight the berserk Hresvelgr. With everyone's combined strength, Gourai manages to win the battle and put a stop to Hresvelgr, who returns to her senses. Shortly afterwards, Gourai is taken by a recall drone to Factory Advance, but luckily it turns out to be a temporary recall for maintenance. Later, on Christmas Eve, Ao holds a Christmas party to welcome Hresvelgr, during which Gourai asks Ao to share her surname. Wanting surnames of their own, the other F.A. Girls decide to set off in search of their own special partners, holding a live show for Ao as a send-off. Meanwhile, another F.A. Girl is in development.
