In a kingdom where science and magic exist side by side, Futaro Uesugi is a struggling student at the Magic Academy barely keeping his finances together. A sudden job offer for a well-paying tutoring position seems like the answer he has been waiting for — until he discovers that his students are none other than his own classmates: the quintuplets. Beautiful daughters of a wealthy noble in service to the royal family, all five of them hate studying, all five of them are on the verge of failing, and all five of them are hiding a secret that Futaro is about to stumble into.
