Nanaka 6/17 (ななか6/17 Nanaka Jūnana-bun no Roku?) is a 12-tankoubon manga and 12-episode anime series created by Ken Yagami.

The manga was published by Akita Shoten, while the anime was aired on TV Tokyo. The series is licensed for distribution in the United States by ADV Films. The manga was initially licensed by Studio Ironcat, but all plans on release were dropped with the company's fall.


The story focuses on a cold and distant 17-year-old girl, Nanaka Kirisato, who only cares about studying to get good grades in school and being accepted into a good college. Nenji, her childhood friend, doesn't really care about school and will often get into fights.

Soon, Nanaka has an accident that causes her mind and memories to be reverted back to the time when she was 6 years old. Nenji ends up becoming the 6-year-old Nanaka's babysitter until they can find a way to turn her back into the 17-year-old Nanaka, which causes trouble and comedic situations.



  • Nanaka Kirisato (霧里七華?)

Voiced by: Chiemi Chiba (Japanese), Monica Rial (English)
Nanaka is a senior high school student. For her, studying is the most important thing in the world so she has few friends. One day, after a fight with Nenji, she falls down a flight of stairs. This is what causes her memory to be lost back to the time when she was 6 years old. This 6-year-old Nanaka is a very spirited troublemaker and is obsessed with a children's anime TV-show called Magical Domiko. The 6-year-old Nanaka is fond of saying the non-sensical words "hayaya" and "hawawa", and is recognizable by her side pigtail and wider eyes.

Voiced by: Kenichi Suzumura (Japanese), Chris Patton (English)
Nenji is Nanaka's classmate and childhood friend. He is a delinquent, but after Nanaka's accident, he seems to settle down quite a bit. Nanaka's father asks him to keep Nanaka's accident secret from other people and take care of her at school. Nenji is occasionally referred to as 'Wild Hair Nenji' by some of the other characters because he has long, spiky hair reminiscent of certain stylized Shōnen anime characters.
