Sakurai Meina, the sole female hero Magna Pink of the superhero team Magnaman fighting against the evil empire Dustoras, saves a group of people attacked by enemy soldiers—only to realize it was a trap. The people she rescued are actually henchmen of the monster Mangilla, who sneaks up and chokes Meina from behind. As she desperately tries to transform, her bracelet is knocked away, preventing her transformation and leaving her captured by Mangilla. Enduring intense torture, Meina suddenly struggles with an overwhelming urge to urinate. Noticing her distress, Mangilla presses down on her abdomen and tickles her mercilessly until her muscles give out. Unable to hold it any longer, Meina involuntarily wets herself and loses consciousness.
