Tulip Prison—a special penitentiary filled with sex criminals from all over Japan who have been deemed too perverted to rehabilitate. As the "phantom precinct" of the justice system, its facilities occupy an inescapable island that stands alone on the open sea. Shuichiro Minato—a young man who lives in Tokyo. The police gave him the nickname "Exhibitiman." Fundamentally opposed to the idea of clothing, he is driven by a powerful compulsion to get naked. This obsession has led him to risk his very life to streak, and one day, amid the Christmas lighting of a beautiful winter night, it led him to be arrested for indecent exposure and assault. Shuichiro defended himself in court, describing his acts of exhibitionism as self-expression—art—but no one understood him. He was sentenced to ten years of penal servitude for resisting arrest and his repeated acts of public indecency. What's more, he was deemed too far gone to rehabilitate... and thrown into Tulip Prison. In a modern-day dungeon with monsters around every corner, can one brave exhibitionist survive? Society calls these prisoners ‘‘HENTAI’’—sicko perverts—and whatever the future holds, one thing is for sure: This prison ain't no paradise.
