An exorcist has just defeated a dangerous demon when another one suddenly appears from the ceiling. This new demon is not like the previous one, as it lacks horns and wears tattered clothes. It's also hungry and claims to seek the exorcist's soul. Despite its threatening appearance, however, the exorcist feels sympathy for the creature and decides to buy it some food instead of killing it. The demon is grateful and becomes determined to assist the exorcist in any way possible.
