Misa corners Asmodeus but Gilad stops her before she is about to obliterate him. Now Misa has to infiltrate Chastity Rock, a prison for succubi, and track down Asmodeus who uses his shape-shifting and absorption powers to stay hidden and grow stronger, feeding on other prisoners while plotting revenge.

Will Misa be able infiltrate the prison and find out where Asmodeus is lurking before it's too late to stop him?

Misa uses a diverse set of skills and attacks to defeat her opponents, dealing damage proportional to her magic power level in each fight. As you progress through the levels, the story advances and the challenges become trickier to overcome. Use your wit and planning to confront enemies with ingenuity and the necessary force.

Combat

Fight all kinds of demons that use debuffs to weaken and incapacitate Misa. If you lose, you will witness a brief cutscene and return to the stage progress screen, where you can retry the same level. If you win, you progress the story and bring Misa one step closer to her goal. Be sure to remove any negative status effects before proceeding.

Replenish Strength

When magic power has dropped severely, you can replenish it by calling Warden Zaki on the Chapter map and entering a covenant of magic power exchange. Calling Warden Zaki for help will be unlocked after the first encounter.

Bonus Costume

Upon clearing the story for the first time, Misa's bonus costume will be unlocked for the next run of the story, providing additional enrichment to the replay value.
