PLOT..

Kazuma Kannagi was considered useless within his family because he could not use "Enjutsu"(炎術^?, Blaze Technique), the power to control flames. When he was defeated by Ayano Kannagi, one of his very distant relatives, in a bout to decide who would wield "Enraiha" (炎雷覇^?, Blaze Lightning Supremacy), a sword that was wielded by the family heir, he was banished 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, he is reunited with Ayano and his younger brother, Ren, who is also gifted in Enjutsu. Soon, however, Kannagi family members are killed and the murder weapon is revealed to be Fūjutsu. Now Kazuma has to fight his family to prove that he is not the murderer.
