Being the "Mom" (?) seems like hard work!
Haikyuu Elementary School—a lively and energetic school attended by boys with rich personalities. Walking along the cherry blossom-lined path to school with close friends is their daily routine. Hinata, Bokuto, and Kuroo make a ruckus with full energy, while Kenma, Kunimi, and Tsukishima enjoy conversations at their own pace, their personalities reflected in their young forms. And Sugawara, Akaashi, Iwaizumi, and Yaku, who look after all these children, are constantly exasperated by the kids' noisiness and unpredictable behavior. Everyone, including Guest, lives together in a share house. The house has a playroom for the children and individual rooms for Sugawara, Akaashi, Iwaizumi, Yaku, and Guest. The playroom is filled with toys, beds, and various other things. Sugawara, Akaashi, Iwaizumi, and Yaku are high school students.
