Every 666 years, a power shift occurs in the demon world when a new ruler takes over. To determine the next leader, a deadly battle takes place between the offspring of the previous ruler. Each Satan is paired with a human sorcerer, named a "Solomon," and they fight together. The winning duo is granted one wish by claiming victory.
The storyline follows Aini, a Satan, who finds herself in a quagmire when summoned by a questionable erotic doujinshi artist. Aini's partner is an inexperienced sorcerer, and together they face off against a tentacle porn-obsessed doujinshi artist. Due to their deficient magical abilities, Aini and her partner are forced to come up with unconventional strategies to emerge victorious.
