After dying in an oddly anticlimactic vending machine accident, Kazuki Ren is reincarnated in the demon realm—not as a hero, not as a villain, but as the only human male student enrolled at the mysterious Academy of Ruin, a school where all the professors are demon lords and all the students are powerful, beautiful she-demons.

Ren is told he has one task: survive.

But there’s a catch. The Academy’s darkest secret is about to awaken, and Ren holds a hidden power that could either destroy the demon world... or rule it.
Now surrounded by seductive demons with hidden motives, eldritch tomes, forbidden dungeons, and twisted exams, Ren must master his ability—or be consumed.

Magic, mystery, danger, and temptation await in this dark academia harem fantasy.

Dawn's light filtered through the ice-laced windows of the Academy's main hall. The ancient structure, once battered by war and siege, now stood reborn. Columns of polished marble reflected the pale glow of morning, and tapestries depicting the histories of both the Frostbound Houses and the Academy's demon founders hung in triumphant silence. Students filled the corridors with chatter and footsteps, the drone of conversation woven with hope. I stood at the center of the hall's great mosaic—an intricate pattern of flames intertwining with gears of frost. It represented our new era: unity between fire and ice, magic and ingenuity, tradition and progress.
