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.

After being briefly delayed by Ayano's surprise attack, Kazuma, together with Ayano and Ren, faces off against Misao, who is still powerless against him. Michael Harley informs Misao that she will never be able to defeat Kazuma, and subsequently uses Misao's body and her accumulated life energy to create a dragon. Ayano, Ren and Kazuma must destroy the dragon while not harming Misao.

Ayano is sent to investigate a hitodama that has been sighted at Seiryō Academy, her own school. Kazuma is hired as her bodyguard, and even Ayano's friends, Yukari and Nanase tag along. However, the disturbance turns out to be the work of the mischievous pixie Tiana, and Ayano becomes a target for her pranks.

Ren meets a young girl, Ayumi, who has escaped from the Tsuwabuki family, the most powerful clan of earth mages. Seeing how badly they treat her, Ren decides to use his power to protect her at the cost of starting a conflict between the Kannagi and Tsuwabuki families. Meanwhile, Kazuma accepts a mission from Tiana's tribe to retrieve the pixie heirloom stolen by the Tsuwabuki family.

Ayumi tells Ren she wants to go to the beach, where they meet the Tsuwabukis. It is then that Ayumi is revealed to not be human, but rather a clone, created for the Taisai ritual for sealing Mount Fuji. Meanwhile, Kazuma is still watching the Tsuwabukis and waiting for the treasure.
