With the Demon Lord gone, the Demon Lord’s Castle has fallen into chaos as monsters wage a civil war to claim the throne.
Players take on the role of Lethe, a young Demon girl who was once the Demon Lord’s younger sister, and use her power of domination to subjugate defeated monsters and form a party of her own.
In battle, players can defeat hostile monsters and immediately turn useful ones into allies through domination. Dominated monsters each have their own stats, skills, and traits, allowing players to combine them into a party with various roles such as offense, defense, and support.
After clearing a stage or reaching game over, players return to their base, where they can train dominated monsters, prepare the party for the next battle, and craft items needed for combat.
Dominate more monsters, grow your base, and raise Lethe’s new Demon Lord army.
Lethe can use her power of domination on enemies defeated in battle.
Dominated monsters recover their health, become allies, and immediately join the player’s side in combat.
Not only regular monsters, but also powerful elite enemies and boss monsters can be dominated.
Defeat threatening foes, subjugate them, and turn them into Lethe’s loyal minions.

Monsters have different stats, skills, and traits depending on their type.
Each monster can play a different role, such as protecting allies with high defense and taunt abilities, supporting the party with healing skills, or overwhelming enemies with powerful attacks.
Even monsters of the same type can appear with different skills and traits, giving players new reasons to dominate monsters they have already encountered before.
Dominate monsters that fit your playstyle and build your own Demon Party.
