"After passing her entrance exam, Yuno enrolls 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, peers, overly hyper teachers, and closely follows the mundane lives of the high school girls. This season also takes place in Yuno's first year at high school, and overlaps with season one of the show."

Hidamari Sketch x 365 is the series title of the second season of the Hidamari Sketch anime consisting of 13 episodes. It debuted in Japan July 3, 2008, and ran through September, with a set of OVA episodes released in March 2009. Like its predecessor, it takes place during Yuno's freshman year and it is not in chronological order.
It fills in some of the story gaps in the first season, notably by telling the story of how Yuno moved into the Hidamari Apartments, met Miyako, and began her career as a Yamabuki High School student. It also includes events referenced but not shown in the first season.
