Kazuma Yagami
Kazuma Yagami is the primary male protagonist of the Kaze no Stigma series and is regarded as the Yagami family's most brilliant member. After extensive training in China, he returns to Japan as an extraordinarily powerful wind magic practitioner, having formed a contract with the Spirit King of Fire, exactly as the first Yagami head had done before.
Kazuma is revealed to be bitter, unpleasant, and selfish throughout the series, which arises from the Yagamis' frequent harsh treatment of him owing to his inability to utilize fire magic and his subsequent disownment. While it was for his own good because he would not have been in a favorable situation if he had remained a Yagami, as far as he knew, his parents abandoned him because he was weak, and he resolved to grow stronger as a result.
Kazuma's powers as a Fjutsushi (Wind Technique Practitioner) are enormous, and he is by far the most powerful character in the series, capable of fighting as a one-man army due to his might being on another level when compared to the other characters. He is without a doubt the most powerful Spirit Practioner to ever exist, and he is talented enough to study additional elements besides fire in the novel.
Kazuma Yagami is revealed to be a Contractor, a very uncommon individual who has signed into a contract with the "Kaze no Seirei-" (Wind Spirit King), which means he has been entrusted with all of the Wind Spirit's power as the spirit king of the wind's domain.
