The Quintessential Quintuplets (Volume 3) - Negi Haruba

A high school romantic comedy with five times the cute girls! A high school boy must work part-time to help five sisters study so they can graduate, but the only thing these quintuplets have in common is that they all hate studying! Working hard finally feels like it's paying off! After an exciting fireworks festival, Futaro feels like he's come to an understanding with the sisters. Unfortunately for the study group, midterm exams are right around the corner and the stakes are higher than ever. The quintuplets' father gives Futaro an ultimatum: If even one of my daughters fails...you're fired! But to Futaro's surprise, after a sleepover at the girls' house, some of them are actually stepping up to help him!
