Gag Manga Biyori: Jump Festa 2002 Special

Rising idol Saki expects an autograph event to be a triumph, only to face the horror of an empty crowd. Her desperate editor responds with increasingly terrible ideas, eventually dragging her into an absurd autograph showdown against the dangerously enthusiastic Bururu.

Elsewhere, a group of reckless teenagers manages to summon Satan and immediately realizes they have no idea how to send him back. Every improvised solution only makes their supernatural guest angrier, turning a foolish experiment into a frantic comedy of errors where common sense never has a chance to catch up.
