Just barely squeaking past the academy's transfer exam, Soma causes and uproar at the opening ceremony by making a brash speech in front of the entire class. In his very first class, he's paired with Tadokoro Megumi, a girl who is at risk of expulsion and is intent on keeping a low profile in order to survive.

The training camp is considered the first trial by fire for students in Totsuki's high school division. Dozens of students are said to be expelled and sent away every day, and the number of students is said to be reduced below half by the camp's end. Intent on survival, Soma and his friends embark on their journey to the hellish camp in one of Totsuki Resorts' hotels.
