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. A Steel Angel built by Dr. Ayanokouji and equipped with a Mark II Heart, she is awakened by Nakahito's kiss in the first episode and immediately becomes possessive of him while simultaneously pledging her love and service to him.

Amagi and the General decide to use the largest of the seized Angel Hearts to give Saki as much power as possible. Saki and Kurumi fight, with the latter being defeated easily due to Nakahito's still-standing order to not fight. The victory is short-lived however, as Saki's improper activation causes her to collapse. Kurumi kisses Saki, and her Mark II Heart re-energizes Saki's Angel Heart. The action permanently activates Saki, and the master-servant relationship is reinstated, with Saki pledging her loyalty and love to Kurumi. Kurumi largely ignores this vow, but the two mutually call each other "sister" from then on. Saki is very quiet, the antithesis of
