Summary: Kazuma Kannagi was the eldest son of the Kannagi family and presumed heir. However, due to his inability to use "Enjutsu" (炎術, Blaze Technique), the power to control flames, he was considered to be useless within his family. Despite his inability to wield fire, his father insisted on him competing for the right to wield "Enraiha" (炎雷覇, Blaze Lightning Supremacy), a powerful heirloom sword traditionally wielded by the family heir. The 18-year-old Kazuma was soundly defeated by 14-year-old Ayano Kannagi, his second cousin, and his father banished him from the family.

Four years later, he returns as a master of "Fūjutsu" (風術, Wind Technique), the power to control wind, and with a new name: Kazuma Yagami. Soon after his return, several Kannagi family members are killed by someone using Fūjutsu and Kazuma is presumed to have committed the murders in revenge for his banishment. Though innocent of the murders, he is confronted by various members of his former family who wish to fight him. However, the only person that Kazuma wants to fight is his father, the strongest Enjutsu user and whom he later defeats in a duel.

Kazuma is revealed to be a Contractor, a rare individual who has entered into a contract with the "Kaze no Seirei-Ō" (風の霊魂王, Wind Spirit King). Due to this, Kazuma is able to draw upon the wind spirits around him, which amplifies his inherent powers, and allows him to heal his wounds. When using this power, his eyes turn azure blue. However, this ability puts a strain on his body, as it is his stamina and will that limits the amount of power available to him.

After the duel Kazuma returns to his hotel and finds that his younger brother, Ren Kannagi, an extremely powerful Enjutsu user in his own right, has been eagerly waiting to see his adored elder brother again. Their reunion is interrupted by the Fūjutsu user who killed the other Kannagi and who kidnaps Ren. Kazuma returns to his former home to consult with the head of the Kannagi. Ayano intrudes into their meeting and, believing Kazuma to be guilty of the murders, attacks him on sight. Remonstrated by the family head, and her father, Ayano works with Kazuma to rescue Ren.

Further story arcs revolve around Kazuma, Ayano and Ren and the growing relationship between them.
