Devil Decides to Die S

You can challenge all the stages without any limit.

You’re the strongest entity on earth, and you’ve decided to die for some reason. A group of heroes has come to defeat you, but they’re inexperienced and not at all equipped to achieve their goal.

You have to help them gain experience and become strong enough to kill you by sending monsters to them strategically.

There’s only one rule in this game: help your enemies become strong.
