Kazuma comes back to his family as the one thing they despise, proves he was right to leave, and never lets them forget it. The revenge isn't loud or destructive; it's him being casually better at everything they built their name on. Ayano spent four years as the golden child while he was reforging himself into someone untouchable, and the tension between them is the only thing in the story that actually matters.

Kazuma returns to Japan after four years in exile, transformed from a talentless member of a fire-wielding family into an exceptionally powerful wind user. His family, the Kannagi clan, cast him out after he failed at fire magic and lost a duel to his younger cousin Ayano, but now he's back with a contract with the Spirit of Wind. The timing couldn't be worse. Kannagi members are being murdered by someone using wind, and all fingers point at Kazuma as the obvious suspect. His hot-headed cousin Ayano, heir to the house, is among those convinced he is taking revenge. Kazuma insists he had nothing to do with the murders, and clearing his name means helping the very family he despises find the true killer. Caught between suspicion and a looming all-out war with the Kannagi, Kazuma and Ayano end up right in the middle of the conflict. Action, fantasy and romance mix as old wounds resurface.
