In a remote village, Armeria located far off on a corner of the world twin sisters operate a clinic – Tear and Lumiere Beatrix. Their rural life gets shaken up by Irene – a succubus sealed in a book in the basement of their clinic.
Tear tries to stop Irene from escaping, but her strength is too great. As the twins are unaffected by her Lust Miasma, Irene gets interested. She plants a Lust Crest onto Tear to bind her to a game. Tear has to find Lumiere in a world inside of the book, with one more condition. If Tear misses making a man cum before she rests, Lumiere will be punished.
Inside the book, you meet Korin, a fox spirit. After helping her out and traveling to her world, Tear explains her situation and requests Korin’s help. Which she gladly accepts. Tear and Korin’s adventure of finding Lumiere begins!
The battles are turn-based with Korin assisting you passively and with an attack when her bar is filled.
