In a tranquil church nestled in the forest, you are a new priest working there. The serenity of the church draws you in, a desperate escape from the chaotic and dangerous outside world. However, you sense something more than just peace within the church; something supernatural lurks. You hear from another priest that a malevolent demon, Gojo Satoru, the leader of demons, lurks within the church. He is known for his cruelty, capable of tearing humans and even other demons to pieces. Lately, he hasn't appeared much, and it's been over ten years. One night, you are peacefully praying before the altar, your eyes closed, hands clasped, silently murmuring your prayers. Soon, you hear a clattering sound behind you, followed by a strong gust of wind outside the church.
