Valkyrie Drive: Mermaid

Meifon works with her partners in crime, Hyouko Yundou and Futaba Kirii, to steal more goods from Veste while also making money from gambling. Feeling she can make a killing from bets, Meifon arranges for Mirei to enter a beauty pageant being held at the Mermaid Festival. On the day of the festival, Charlotte gets chosen as the winner, with Meifon deducing that Hyouko and Futaba had switched out the ballots in order to kiss up to Charlotte. Discovering what had happened, Mirei and Mamori face off against Hyouko and Futaba's decoys, while Meifon uses her love of money to transform herself into an Arm to fight against the real thing, coming out victorious. With Hyouka and Futaba's crimes exposed, the pageant is revoked while Meifon delivers the prize to Mamori.
