S1·E1 The Wind's Return

Kazuma Kannagi, who was exiled four years earlier for his defeat and his lack of talent in fire magic, returns to Japan with a changed name and tremendous skill in wind magic. Killings at the Kannagi house by a powerful wind user lead his former family to believe Kazuma is taking revenge for his exile. Although he claims to be innocent, Kazuma prepares for an all out war with the Kannagi family.
