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

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.: Chicchana Mune no Tokimeki tells the story of two 12 years old girls, Yui and Hanabi, it's a story how they found their first love and how they live that love.

Storie: 6 out of 10

There are many better romance story but what i liked about 12-sai is that they tell the story of two girls that fell in love for the first time, and each girl have different problems. It is a story show the innocence of a 12 years old girl (or at least what it should be).
The development is really slow, 1 little problem per episode and the end is always the read more

Story : 4/10
The story was too cliche, literally and it basically shows how 12 years olds go date and have relationships but I like the fact how they make everything innocent, like the fact that they say Yui just gets much more mature and not say she's getting menstruation for that.. and I ship Tsutsumi with Ayase (o3o).

Art : 8/10
I swear! The eyes becomes smaller and bigger for some reason. I promise my eyes aren't lying.

Sound : 5/10
The like the opening music but not the ending :(

Character : 8/10
Character Designs were cute. (because I'm a shota/loli-con) Personalities were fine, except for those other girl characters. read more
