Great granddaughter of either Nakahito or Kamihito, Nako is a soft-spoken, shy, and clumsy 9th grade student at an all-girls school. She lives at the old Kagura shrine with her mother, Misaki (which proves even further that dark blue hair just runs in the family), and lives next door to her very rich neighbor and best friend, Uruka. Nako is also a very skilled cellist, and may prove to one day be famous. The day she found Kurumi was the day she gave her first kiss(es), and from then on was blessed (or cursed) with being the new master of Steel Angel Kurumi. Now being the receiver of the same affection that was given to her great ancestor Nakahito, Nako is constantly chased and protected by Kurumi.
