Idle Devils

Idle Devils is a turn-based fantasy RPG for players who like monster girl casts and strategic combat over fast action. The tone stays adventurous and a little grand, with the stakes of a broken seal running through it.

Story

The Demon World was consumed by a violent miasma, forcing the Demon King to seal the infected into seven hells using the staff of stars. Two hundred years later that seal breaks, the Demon King is lost trying to stop it, and the Demon World descends into chaos again. A new ruler must be chosen, decided by whoever proves capable of sealing the seven hells once more.

Gameplay

Players take command of a growing roster of monster girl allies, building teams and working through turn-based battles as they push toward each of the seven hells. Progress leans on idle mechanics for growth alongside deliberate, strategic fights, with the animated 2D cast giving each encounter its own personality. The core loop mixes party management with combat planning rather than direct real-time control.

Features
