Gag Manga Biyori: Jump Festa 2002 Special

In a twist of fate, aspiring idol Saki finds herself facing an empty room during her autograph session, leaving her flustered editor scrambling for a solution. In a misguided attempt to draw in fans, he resorts to threatening a nearby elementary school student, but that plan quickly falls flat. Desperate, he concocts a wild idea: a showdown between Saki and a deranged rival, Bururu, who also dreams of stardom.

As if that weren't chaotic enough, a group of reckless teenagers unwittingly attempts to summon the Devil, leading to a series of increasingly absurd mishaps. With the infernal being growing more agitated with each failed attempt to send him back to his realm, Saki and her editor must navigate this bizarre series of events. Will they manage to escape the chaos and restore order, or will their antics land them in deeper trouble?
