Saki, a rising idol, holds an autograph session that draws absolutely no fans, leaving her unfortunate editor completely clueless. The young man, in his questionable wisdom, decides that intimidating a nearby elementary school kid is the best solution. After that tactic fails, his only remaining option is to stage an autograph face-off between Saki and Bururu, a deranged idol aspirant. Later, a reckless teenager botches an attempt to summon Satan, and he along with his companions must figure out how to send the devil back to the underworld. Their efforts only make the demon more enraged, leaving them to wonder if they will survive the encounter unharmed.
