Ai ga Suwarechau!/My love will be sucked out! - S1.E40

Petora, continuing in his guise as Counselor Iwamoto, institutes absurd school rules with his new henchman, Sojiki, by his side. When Limone, Jama-P, and the Love Angels take them on in battle, they end up getting sucked into a minus energy wave dimension. Limone conjures a barrier to protect the Love Angels, but is overcome by Sojiki's attacks. All seems lost until the Saint Something Four manifests itself on its own, defeating Sojiki. As a result of his injuries, Limone's secret identity is revealed to the Love Angels.
