The second series to a mostly ignored first season of a show which was once an OVA. Yes, this franchise has been around for a few years, but also neglected massively, and I can see why.

I have not watched the OVA, so I can only base this review on the first season's experience as well as this series.

Story - 6/10

Not anything great story wise, just a love story of 4 12 year olds falling in love for the first time, with the bad guidance of the females' friend Marin and to the hatred of Kokoa, who is in love with Takao, and would do anything read more

The second season of 12-sai keeps things the similar to the first season. So if you expect some huge development for the couples or deep relationship drama, you most likely will be disappointed. Although at some points it actually took a more serious approach to their relationships. (fights, thoughts about the future and how long their love will last, approval by family)

Those things are still handled really lightheartedly and resolved in a very short time, so mostly you'll still see the same rosey childish approach. Yes - it's childish, it's cringy, but that's exactly what this show is about. Love from the view of little read more

12-Sai.: Chicchana Mune no Tokimeki 2nd Season continues off from its prequel. It is about 6th graders growing up and learning 'bout love and are trying to understand what "adulthood" is about. Firstly, the plot sucks. The drama has been always shit and the good moments are too short (mine is like last few episodes).

Main plot consists of:
1. Introduction and pairing partners,
2. Dates.

That's it. The others are just fillers with side characters, and almost every side-character is annoying. You can just see episodes that pair the students at the start and then skip to the last episode, and you'll see the main plot. The other read more

So lets keep in consideration that this anime is 100% for a younger audience (specifically probably 12 yr old females). I feel like a lot of people ignore this aspect when rating: So anyway
Story 7: There wasn't really much plot development to the second season. There was some drama put in but essentially it was just showing the characters remaining as couples and growing as couples. That was basically the point of the anime so it fulfilled it's duty.
Art: The art was consistent and fine- my only issues was the wonky eyes. The problem is the eyes are large, wide-set, and basic and the eyebrows read more
