Yuuhi Amamiya

The main character of the story. A reclusive, glasses-wearing college student who initially refuses Noi Crezant's request to help save the world. The reason behind his unsocial nature is his grandfather, who raised Yuuhi and believed that having friends was useless. Eventually, he changes his mind in order to help Samidare Asahina, who he usually refers to as Princess.

His ability is called domain control. He can exert a weak telekinetic force on a small bubble of air, just enough to hold himself above the ground for a few seconds or slow down an enemy's attack. Although his overall combat skills are much weaker than that of most of the other characters.
