Season 1 of Hidamari Sketch premiered on January 12, 2007.

Accepted to a high school specializing in the arts, Yuno moves into a nearby apartment complex to make her commute easier. Just a few days into her new routine, she quickly discovers that creativity doesn’t end with the art school bell! Her neighbors — Sae, Hiro, and Miya — are all fellow students, and each has her own hilarious quirks. And eccentricity clearly rules this school; Yuno’s homeroom teach is a cosplay otaku and the principal is just…weird. Will the quiet Yuno be able to handle this creatively kooky cast of characters?

Season 2 of Hidamari Sketch premiered on July 4, 2008.

After passing her entrance exam, Yuno enrols at Yamabuki High School as part of an art degree. She stays at the Hidamari Apartments along with best friend Miyako, and seniors Hiro and Sae. Each episode follows a day in her life as she mingles with her friends, close peers, overly hyper teachers and closely follows the mundane lives of the high school girls. (Note: This season also takes place in Yuno's first year at high school, and overlaps with season one of the show).

Season 4 of Hidamari Sketch premiered on October 5, 2012.

Studying at the Yamabuki Arts High School has been a dream-come-true for Yuno, and she's learned so much already! And not just from her instructors, but from her friends and neighbors who've become her second family and made the Hidamari Apartments such a safe and nurturing home. But as the day of her "big sisters" Sae and Hiro's graduation draws slowly closer, it's time for Yuno to start seriously taking on the same role for Nazuna, Nori and the other budding young artists who've entered Hidemari's protective cocoon. And it's also time to tackle some really challenging artistic assignments. That doesn't mean there won't still be time for fun with Miyako and all the others, but it's definitely time to pencil in her plans for the future. And sometimes that means you have to put the art before the course!
