Photon: The Idiot Adventures, known in Japan as , is a Japanese original video animation (OVA) series created by Masaki Kajishima. The series follows Photon, a boy who possesses superhuman strength, but is extremely simple-minded. He engages in heroic adventures of different varieties. He marries a rebel space pilot named Keyne, and becomes involved in fighting an evil wannabe galactic emperor and his "bumbling henchmen". Photon's marriage to Keyne is slightly odd, as Keyne is more mature than Photon. Yet Photon only sees Keyne as more like Aun's sister (who used to be Aun and Photon's guardian, whom he cared for greatly).

The ending song, "Pinch!", is performed by Yui Horie. A manga based on the anime was written by Hiroshi Kanno.

Main characters

  • (): The protagonist, he is extremely strong and fights using a quarterstaff made of black crystal. The word ('idiot') was scribbled across his forehead by Aun in black ink as he was trying to lead her back home. His strength is tremendous, to a point where he is able to crack a crystal barrier with his bare hands. He is also able to withstand even the strongest blasts of Aho energy, even when it is focused directly on him. It is later revealed that he was the source of the un-Aho, which is the reason why Aun's stasis field has no effect on him. Angry at Aun for writing the word 'idiot' in permanent ink, he inscribes the same word on Keyne's forehead, inadvertently marrying her in the process. Though he is simple-minded, he is very trustworthy and loyal to those he promises to protect.
  • (): Photon's spoiled, high-strung, flighty childhood friend, she has the ability to create stasis fields. Humorously, she is not immune to her own stasis fields and can paradoxically trap herself (and everything around her) in a perpetual stasis field. Photon is the only one who is immune to her stasis field and also is the only one who can get her and keep her out of such messes. In order to cancel out her stasis fields, he has to knock her on the head with his staff. Aun has a tendency to fall in love with every handsome man she encounters, which always ends up in disappointment for her when they turn her down. She also behaves in a tsundere-like manner towards Photon, hinting that she may have feelings for him.
