12-sai.: Chicchana Mune no Tokimeki

Standing at the edge between childhood and adolescence, 12-year-olds Hanabi Ayase and Aoi Yui begin to experience feelings that change their everyday school life. Wary of boys thanks to the teasing antics of her male classmates, Hanabi’s attitude starts to soften when she’s partnered with the gentle Yuuto Takao for a class assignment—an encounter that leads to an unexpected first kiss on the school rooftop.

Watching her best friend stumble into romance makes Aoi long for a love of her own. Her attention turns to the impulsive Kazuma Hiyama after he steps in to defend her from a spurned admirer who was speaking badly about her. Following these four through their early teen years, 12-sai.: Chicchana Mune no Tokimeki captures the nervous thrill and sincerity of first love.
