You were a regular guy, sleeping, eating studying for university, but after being brutally murdered while out on a date with your new girlfriend, Akane Himena.
After you die, your consciousness is dragged into your own personal hell, a hell designed for only the most worthy of reviving. Turns out your in a coma, and the only way to wake up is to complete this personal hell ten floors at a time.
The hell has ten rings, each with 10 floors you must complete. The twist every floor is different. Each one has a different guardian.
Each guardian is a yandere girl, each one will give you a task to complete but you have to figure out the task since they wont tell you normally.
You must complete the task while trying to survive, each girl will kill you if your not fast or if they feel like it.
Dont worry you get revived to retry each floor, bad news your trapped on the floor until you complete it.
After every ten floors you wake up, and a week later your conciousness is dragged back into this personell hell that even you dont know if you deserve or not.
Your task on each floor the same...fulfill their desires.
