Reaching a period of life where they are neither a child nor an adult, 12-year-old Hanabi Ayase and Aoi Yui meet with life-changing events. Due to the mischievous demeanor of her male classmates, Ayase does not think highly of the opposite sex. However, her perspective begins to change after she is paired with the kind-hearted Takao Yuuto for a class assignment and unexpectedly shared their first kisses with each other on the school rooftop.

With her best friend discovering love, Aoi yearns to seek her own. She finds herself falling in love with the rash Kazuma Hiyama after protecting her from a rejected suitor who had talked behind her back.

12-sai.: Chicchana Mune no Tokimeki follows the four in this phase of adolescence. As they grow up alongside each other, this sweet romance depicts the innocence and excitement of first love.

If I had to choose a word to describe this anime, it would be "cute". This anime was so adorable and cute that it really touched my heart. I judge anime based on enjoyment and whether or not it executes it's stated genres to perfection. For example, This anime was romance and it gave us a lot of romantic scenes. I fell in love with all the romance scene. The characters where also adorable and I imagined myself as the heroine, Ayase.
This anime explores topics like first love, growing up and friendships and relationships at a young age. I know a lot of people read more

This anime is definitely for a younger demographic- specifically 12 year old females- and with that being said I think the anime was great.
Story 7: It had a very basic plot with not too much drama, the main drama was the classmates being jerks sometimes. Relationships were established pretty early on and the plot was mostly about them, young 12 year olds, learning about it.
Art: The art was decent. The only problem is the eyes are large, wide-set, and basic and the eyebrows are just lines so when the animation on the eyes isn't perfect it is very noticeable. But eyes are often wonky read more

Keep in mind that this is a romance where the main characters are 12 year olds. Think back to when you were that age, and how you behaved (especially concerning love) back then. If that sounds annoying, embarassing or cringy to you, then this show probably won't be a good choice for you.

There's really not much more to say about it than that. There is no depth or tragic backstory to the characters, or some fancy drama build around them. It's plain and simple, 2 couples of kids falling in love, and experiencing what it means to have a boyfriend/girlfriend and being in love in read more

12 years old???, then why do they act more mature than that????.

Ok look, LA knows this anime isn't for LA's demographic but LA is kinda a sucker for romance anime and LA watched the ONA for this years ago and wanted to see how this would get the full anime treatment that Houkago no Pleiades did.

12-sai follows the relationships of 12 year olds of Hanabi Ayase voiced by Ai Kakuma and Yuuto Takao voiced by Soma Saito as well as Hanabi's friend of Yui Aoi voiced by Juri Kimura and Kazuma Hiyama voiced by Shun Horie and follows their experiences and obstacles in first read more
