Valkyrie Drive: Mermaid

Sixteen-year-old Mamori Tokonome has grown used to being mocked at school for a surname that can be read as “virgin,” but her life takes a far stranger turn when she’s abducted during gym class. She comes to on Mermaid, a remote tropical island where she’s immediately thrust into danger with no idea why she’s there.

Her only lifeline is the composed and elusive Mirei Shikishima, who reveals Mamori’s hidden “Exter” power with a kiss—triggering a transformation that turns Mamori into a weapon, a cutlass born from arousal. To stay alive amid Mermaid’s shifting alliances and threats, the pair must rely on that intimate connection while crossing paths with figures like Charlotte, the cruel Liberator surrounded by Exters, the cunning and voracious Meifon, the enigmatic Akira Hiiragi, and the provocative biker duo Lady Lady.
