Kokoa Hoto is a positive and energetic girl who becomes friends with anyone in just three seconds. After moving in with the Kafuu family in order to attend high school away from home, she immediately befriends the shy and precocious granddaughter of Rabbit House cafe's founder, Chino Kafuu, who is often seen with the talking rabbit, Tippy, on her head. After beginning to work as a waitress in return for room and board, Kokoa also befriends another part-timer, Rize Tedeza, who has unusual behavior and significant physical capabilities due to her military upbringing; Chiya Ujimatsu, a waitress from a rival cafe who does everything at her own pace; and Sharo Kirima, another waitress at a different cafe who has the air of a noblewoman despite being impoverished. With fluffy silliness and caffeinated fun.
With a new year comes new adventures, especially at the Rabbit House! Since her arrival at the café, Kokoa Hoto has become accustomed to her new life as a waitress even though the Rabbit House isn't the rabbit paradise she initially envisioned it to be. Life is pleasant, and she enjoys spending time both working and playing with her friends and fellow waitresses Chino Kafuu, a cute middle school student with a fuzzy bunny companion named Tippy, and Rize Tedeza, the pig-tailed daughter of a soldier who is readily armed for any scenario. Together with Chiya Ujimatsu and Sharo Kirima, who also work at neighboring cafés in town, the Rabbit House crew gets involved in all sorts of crazy adventures. Throughout these adventures, the girls encounter troubled novelists, rival cafes, secret treasure, and... alcoholic chocolates?
Although the year is coming close to an end, there is no lack of fun for Kokoa Hoto and the other café waitresses! From bazaars to festivals, life is as enjoyable as it gets. As for Chino Kafuu and her middle school friends—the friendly Megumi Natsu and the playful Maya Jouga—they begin to look towards the future and decide on a high school to enroll in. Bonds of friendship and exciting adventures blend into Gochuumon wa Usagi Desu ka? Bloom as the joyful lives of the café waitresses continue.
