Kaze no Stigma by Yamato Takahiro

Translated from Japanese Action Drama Romance Supernatural Magic
Four years ago, Kazuma Kannagi was defeated by his cousin Ayano Kannagi for the right to be the successor of Enraiha, a sword passed down in the Kannagi family. His defeat, along with his lack of talent for En-Jutsu, the fire arts, the Kannagi’s specialty, resulted in his banishment from the family. Now, Kazuma returns as Kazuma Yagami, a skilled master of Fū-Jutsu, the wind arts. At the same time, a number of murders at the Kannagi residence perpetrated by a powerful Fū-Jutsushi cast suspicion on him.
Volume 1-6 makes up the main story. Volume 7-12 are various short stories, also known Kaze no Stigma Ignition.
