The main character. He is a high school (middle school in the manga) student, son of a globe trotting archeologist father. Because his father and older sister travel and his mother is deceased (in the manga she is merely absent) he lives alone in his two story home at the beginning of the story. He is decisive and intelligent, but nonetheless beleaguered and is a similar character to Keiichi Morisato in both personality and situation. He has a crush on Shaorin just after he first meets her and his feelings for her develop even more throughout the series.
