Nanaka 6/17

''Majikaru, Domikaru ! Transform me into an adult !''

Nanaka is a 17-year-old high-school student who's completely obsessed with preparing her college exams, to the point of being looked down upon by her classmates. She's extremely frustrated by her childhood friend Nenji, an immature punk who keeps getting into fights with the local bullies. On a fateful day, Nenji decides he's had enough with Nanaka's nagging, and tells her to sod off.

She doesn't take the news well.

After Fainting dramatically, she hits her head violently on the pavement and has to be taken to the hospital. There, it appears that she has complete amnesia from age 6 and upwards, ending up with the personality she had when she was 6. There's no telling when she will be back to normal, if ever. Nanaka's father urges Nenji to help her recover, and to protect her in the meantime. Nenji manages to cook up an acceptable explanation to Nanaka : they both "magically" grew up from 6 to 17, which is a game they used to play at that age in imitation of her favorite Anime, Magical Domiko. But they still have to grow up mentally.

Hilarity Ensues when she has to go back to school. Most of her classmates misinterpret her childish behaviour as flirtiness and hate her even more. Nenji has great trouble trying to prevent her from perpetually humiliating herself. But the most surprising part is that, however tiresome she can sometimes be, the 6-year-old Nanaka is sweet, cheerful, earnest and as a whole much more loveable than her 17-year-old self. One wonders what the heck went wrong with her growing up. Should Nenji really try to bring her back to normal ?

Nanaka 6/17 is a fun light-hearted (if sometimes bittersweet) comedy about growing up and how much one should change between childhood and adulthood. There's no easy answer though, and it does not end with a forced Happy Ending.

This story was originally published as a 12-volume Manga from 2000 to 2003 before being adapted as a Thirteen Episode Anime in 2003. All thirteen episodes of the English dub are available on YouTube, though the last five episodes are mislabeled.

 * Amemiya is an interesting case : she was actually interested in Nenji ever since in her childhood when he defended her from bad kids, but when meeting him again in High School, she was frightened by him as he has become a violent Delinquent.
