Kanenone Gakuen is an all-male boarding school located in the countryside of Japan. Although an all-male school is nothing new, life can become quite difficult when there are no female students for miles around. In order to help the psychological health of everyone involved, the school board has decided to try and merge with the nearest all-girl boarding school in order to become co-ed. The boys of Kanenone are more than thrilled at the prospect, and the girls are curious as to how interesting school life might become if there were more boys around. Before any serious decisions are made, the girls have been invited to stay at Kanenone for one month as a test. Green Green follows Yuusuke Takazaki and his naughty room mates called the Baka (Idiot) Trio, and their ability to talk to the girls without making complete fools of themselves. But as soon as the school bus with the girls arrives, things become weird, hormonal, and hysterical. In particular, a girl named Midori Chitose leaps off the bus and immediately embraces a very confused Yuusuke. Is he a natural ladies' man, or do the two of them have a shared history that he is not aware of?

The Fourth Industrial Revolution has led to the development of cutting-edge technologies that have rapidly evolved the world. As a result, schools have begun incorporating these technologies into their curriculum, leaving behind the ways of the old. One such institution is the elite Yuyu Girls' Vocational High School, where both Serufu Yua and her childhood friend, Miku "Purin" Suride, have applied. Although the tech-savvy Purin is accepted to Yuyu High, the accident-prone Serufu is rejected and enters the traditional Gatagata Girls' High School instead, driving a wedge into their friendship. On her way to class one day, Serufu gets into a bike accident, and Rei Yasaku, a passerby who attends the same school, fixes her damaged bicycle. Serufu later finds out that Rei has a passion for old-fashioned crafts and is the head of the school's Do-It-Yourself (DIY) Club—which is in danger of closing due to a lack of members. Realizing that this may be her chance to repair her relationship with Purin, Serufu joins the club in hopes of creating projects that could bring them together once more. As the DIY Club welcomes new faces, Serufu learns to build not only handicrafts but also new friendships along the way!
