The primary male protagonist for the show, Nakahito unwittingly becomes the master of Steel Angel Kurumi when he accidentally awakens her with a kiss. Hesitant and unsure of himself, he teaches Kurumi as much as he can while slowly falling in love with the hyperactive girl. A mystic of the Onmyou (yin and yang) tradition, he has no observable powers. Much to his chagrin, his older brother Kamihito boasts great control of spiritual abilities. Although he has latent potential, as evidenced by his awakening of Kurumi, Nakahito's numerous attempts at honing his direct abilities end in failure. Clearly caught between manhood and boyhood, Nakahito seems unsure of how to handle the relentless attention of Kurumi and his other numerous one-sided love interests.
