During Body Improvement Club practice, Mob faints and is left in the club room to recover. The Telepathy Club, permitted to stay in the room which is now being used to store bodybuilding equipment, comments that Mob will never be popular even if he trains his body. Distraught, he is intercepted on his way home by a woman in a smiling mask, who informs him that she can help him become popular. He follows her to an underground meeting area where a cult known as (LOL) has formed in service to a man with the power to make anyone laugh and smile. A reporter from Mob's school, Mezato Ichi, is forcibly converted, but even the cult leader Dimple is unable to convert Mob. It is revealed that Dimple is a high level spirit possessing a man, and he emerges to kill Mob. The strain causes Mob to reach 100% and "explode", unleashing terrible power and exorcising Dimple. This frees the converts of the cult.
