Seventeen-year-old Nanaka Kirisato is a high school student serious about her studies and goals in life. She frequently criticizes her best friend, Nenji Nagihara, for being a childish delinquent who spends his time fighting other boys. Then one day, after a heated argument with Nenji, she falls off a flight of stairs and suffers a brain injury, resulting in her mind reverting to that of a six-year-old. With this in mind, Nanaka's father and Nenji must keep her injury a secret as she struggles to live a normal life and grow up all over again.

I give this anime an 82/100

I first came across this little anime after finishing watching Nobody's Boy Remi on Anime News Network. I had run out of anime to watch and felt like starting on some new ones. Thankfully, Nanaka 6/17 turned out to be a fine little anime for me to watch before school started for me.

Mixed Feelings

This will be a phrase you will hear often in this series, as Nanaka often tends to blurt it out whenever she is under any kind of pressure.

Story 7/10
This title stays tried and true to the basic "memory lost" storyline you probably have seen before, however it does have a unique aspect to it.

Preliminary (4/12 eps)
Do you truly give a fuck about spoilers for Nanaka 6/17? I thought so.

I don't know why this anime in particular hit me as hard as it did. Anime, in general, is so monotonous, gimmicky, and tropey. I've been aware of this for years now. However, something about Nanaka 6/17 really got under my skin. I think it just caught me at a bad time. I'm a little burnout on anime, at the moment. The show isn't doing anything different from your ordinary, run-of-the-mill anime. No, it's just that it's so blatant and lacks any kind of subtlety in it's writing, that it made ...
