Sister Maria follows the whereabouts of her missing friends and steps into the ruins of the deep forest. Protect yourself from the "miasma" emitted by the demon with a holy mask, and descend to the underground where the "original evil" lurks while destroying the attacking demon with the holy sword. ... However, the miasma, which thickens as it progresses, gradually begins to eat away at the pure body of Mary. There is no way to resist your body that has lost its reason, Maria... Hehehe." ［BAD END］
