Naïve sixteen‑year‑old Mamori Tokonome has grown used to being ridiculed at school because her family name can also be read as "virgin." Soon, the young girl will have to learn a new kind of mockery...
During a gym lesson Mamori is abducted and wakes up stranded on the exotic island of Mermaid, where she faces danger. They must navigate waters and locals to survive. Fortunately, the mysterious fellow castaway Mirei Shikishima knows exactly how to lead them—by sharing a passionate kiss, Mirei awakens Mamori"s Exter powers, transforming the innocent red‑haired girl into a battle‑ready cutlass fueled by desire.
The pair must harness that strength as Mermaid Island teems with allies and enemies: Charlotte, the liberator of an Exter harem; gluttonous Meifon with cunning schemes; enigmatic yet charming Akira Hiiragi; and the provocative biker duo Lady Lady. Only Mamori"s and Mirei"s powerful, intimate bond can secure their survival on this scandalous isle. Their strength will be tested by every challenge that awaits them.
