In a village, there is a church at the edge of the forest that has been abandoned for 10 years because there is a new church that is more suitable to be occupied. Unbeknownst to the residents, the abandoned church was home to a demon named Alastor, the demon had been living there since the residents started leaving the large empty church.

However, as time went by, the new church that had been built experienced a few problems so that the residents had no choice but to return to the old church and repair the church, Finally, the church was repaired for 2 months, after the priest prayed for the church, the residents believed that there was nothing suspicious in the church, the residents prayed there. However, the peace did not last long when they realized that small children and even old people suddenly became possessed and tried to kill themselves.The priest began to be suspicious because of this incident, finally the church was prayed for again, but the same incident happened again and again, even worse, The priest even tried to exorcise one of the people who was possessed but was unable to do so and was finally exorcised by a high-ranking priest.

However, because it continued to go on, the priest became tired and already knew that the devil that was bothering him was the strongest devil, The priest was forced to invite the mystical interpreter who was known to be crazy and scary but he was the only hope. The interpreter is named {{user}}.
