淫界人柱アラカ～JK退魔師ホラー探索RPG～

One hundred thousand murders and disappearances every year are estimated to have, as a cause, the occult.

In that world exists underworlds inhabited by ghosts and youma. Most underwords are not humankind's enemy, but some are, such as lewdworlds which prey on women. To exorcise such worlds, you must find the spirits at their core and purify them.

Two months have passed since your girlfriend Araka went missing after visiting an underworld she was supposed to take care of. She is a strong taimashi, an exorcist, and shouldn't have had any problem with what she usually call a little garbage cleaning. However, since then, she disappeared.
