Hatsune Takanashi is a girl who has a soft spot for things that are easy to please, like curry, friends, and most of all, pudding. Excited to broaden her social circle and relish in delectable cuisine, she enrolls in the all-girls boarding school, Kitsuka Academy, situated on a towering mountain. But her journey in high school won't be ordinary. The school's janitor is a young grade-schooler, her opponent uses fermented soybeans as her weapon of choice, and a foreign exchange student struggles with fashion. Hatsune's escapades promise to be new and exhilarating.
