Earth, Photon

The protagonist is extremely strong and fights with a quarterstaff made of black crystal. Aun scribbled the word "baka" (idiot) across his forehead in black ink while he was trying to lead her back home. He can also withstand even the strongest blasts of Aho energy, even when focused directly on him. It was later revealed that he is the source of the un-Aho, which is why Aun's stasis field has no effect on him. Since he was angry at Aun for writing the word idiot in permanent ink, he inscribed 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.
