When he is displaced into Altia, he gains tremendous magical abilities (his magical capacity level is measured at 120,000, his magical power level at 40,000), ranking him as a natural (and very rare) Unique Magician who can directly tap into the elemental magical forces (as opposed to a normal Magician, who has to chant an incantation in order to make use of them). His specialty magic is being a Summoner who can directly call upon elemental spirits - in his case, Aerial - and their powers. Because of his power level giving him such a distinct advantage over most opponents, he considers himself a "cheat" Magician; hence the series' name. ; : : Taichi's agemate, schoolmate and childhood friend, who has long been harboring a crush on him.
