Moguo Iijima, a student at an academy for those with supernatural talents, wields pyrokinesis to generate and manipulate flames—a power he sometimes struggles to contain. His imposing frame, shaven head, and sharp eyes command attention, complemented by shirts emblazoned with fiery motifs. Brash and confrontational, he leans into delinquent stereotypes, using coarse language and physical intimidation to assert dominance. Enrollment followed an incident where he claimed responsibility for a fire ignited by a follower, shielding them from consequences. Fiercely loyal to his henchmen, he leads and protects them, yet relentlessly bullies peers such as Nanao Nakajima, scorching belongings and ridiculing perceived inadequacies.

Pride in his abilities fuels his self-styled title, "Prince of Flames," underscoring his craving for supremacy. His rivalry with cryokinesis user Seiya Kori embodies their elemental clash, sparking frequent confrontations. Despite his aggression, flashes of vulnerability surface—such as retreating when his romantic interest in Nana Hiiragi is exposed—revealing cracks in his defiant facade. He dismisses authority figures like his homeroom teacher, skirting direct defiance to evade punishment.

As a recurring secondary antagonist, Moguo amplifies tensions within the academy’s competitive hierarchy. His actions and relationships reinforce the institution’s cutthroat atmosphere, though his role lacks sustained evolution or redemption. No spin-off, movie, or OVA appearances are documented in existing sources.
