Kaze no stigma (2007)

Overview

Yagami Kazuma was originally part of the Kannagi family, a respected family of fire users who have an affinity to fire; however, after being easily defeated by his cousin Ayano and having no talent whatsoever in fire magic, Kazuma is banished and cast out from his family. Four years later, Kazuma finally returns to Japan, this time as an exceptionally powerful wind user. For the first arc, a series of murders of Kannagi family members have occurred with his arrival. While most of the family, including Ayano, is convinced Kazuma is the culprit, he claims he isn't. These events begin an all-out war against the Kannagi family, with Kazuma and Ayano right in the middle of it.
