Yagami Kazuma, once a member of the esteemed Kannagi clan, renowned for their mastery of fire, was banished and exiled after a swift defeat by his cousin Ayano and a complete lack of aptitude for flame magic. Four years later, he returns to Japan as an exceptionally powerful wind mage. His arrival coincides with a spate of murders among the Kannagi family members. Though most of the clan, including Ayano, suspect him of the killings, Kazuma is in fact innocent. The ensuing mistrust ignites a full‑scale conflict between Kazuma and the Kannagi family, placing him and Ayano at the center of the turmoil. This story is based on Takahiro Yamato’s novel.
