Valkyrie Drive: Mermaid

Valkyrie Drive unfolds on Mermaid Island, a hidden battleground where girls can be transformed into living weapons through a passionate kiss. When naïve 16-year-old Mamori Tokonome is kidnapped during gym class and wakes up stranded under attack, she is forced to rely on the enigmatic Mirei Shikishima, who knows exactly how to trigger Mamori's Exter transformation and turn the shy red-head into a battle-ready cutlass through the power of arousal. As Mamori and Mirei struggle to survive, the island's brutal order becomes clear: every alliance is built around the bond between an Exter and a Liberator, and every encounter can turn into a fight for control, trust, and survival. The pair cross paths with dangerous and unforgettable figures, including Charlotte, the sadistic Liberator of an Exter harem; the gluttonous and crafty Meifon; the mysterious but charismatic Akira Hiiragi; and the erotic biker duo Lady Lady. With rivals surrounding them and temptation weaponized at every turn, Mamori and Mirei's powerful and intimate embrace becomes their only way to endure the scandalous island and the people who rule it.
