Plot
Satou pines for his childhood friend Hime. One day, she says she is moving away, so he follows her into a portal where she is about to be married to a prince. When a demon attacks, Hime gives Satou her ring, granting him light-based powers he uses to defeat the demon. She explains she is a princess from another world who lived on Earth for her own safety. Her world is under attack by demons and she was destined to marry a hero and pass her ring to grant him power.
The prince was supposed to be the hero, but Satou usurped his position. The ring is one out of a set of five. To become powerful enough to save the world, he must marry four other princesses and gain their rings to get power over four of the elements: earth, fire, air, and water.
