Devil Slayer RPG is an idle RPG starring a she-devil with the aim of destroying endless hordes of monsters. You can't directly control the she-devil, but you can upgrade her equipment and skills as she kills enemies on her own, earning gems and experience in the process.

From the very first minute, Devil Slayer RPG is full of action. As soon as you start the game, you'll see how the main character, the she-devil, destroys her enemies with nothing more than her gleaming sword. In the meantime, your only concern is to level up her weapons and armor while also improving her skills and attributes. Various indicators will constantly pop up on the screen to show you which improvements you can apply at any given moment.
