Stigma of the Wind

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.

Kazuma's father, Gemna Kannagi, tries to bring him back to the Kannagi family's main house to answer some questions, but Kazuma wants to fight him instead. He ends up defeating his father with a special wind technique. Later, he meets his brother, Ren Kannagi, again after four years, but the powerful wind user from before kidnaps his brother. Kazuma vows to bring him back.

In order to bring back his kidnapped brother, Kazuma meets with the head of the Kannagi family, Jūgo Kannagi, to exchange information. The rebellion of the Wind Fang clan serving the Kannagi comes to light, and Kazuma proposes a rescue plan based on cooperation between him and Ayano.

Leaving Ayano behind to hold off Ryūya Kazamaki, Kazuma proceeds to rescue Ren. However, with Ayano defeated, Ryūya manages to merge with the released demon. Ayano, Kazuma, and Ren must combine their forces to stop the demon's advance. In a last ditch attempt, Kazuma prepares to activate his contract.

Misao, the sister of one of the Kannagi clansmen killed at the construction site in the first episode, is out to kill Kazuma for revenge. However, neither her own power nor her hired assassins can scratch him. Just as she contemplates suicide, a mysterious boy, Michael Harley, approaches her and offers to fulfill her desires.

The Kannagi family hires Kazuma to investigate a string of murders, but transfer the job to the police investigators and the Ōgami family once it becomes clear that Misao is involved. With her own family planning to eradicate Misao, only Kazuma refuses to give up on her, and only Ayano is powerful enough to stand in Kazuma's way.
