Heroine? Saint? No, I'm an All-Works Maid (And Proud of It)! (Manga) Vol. 4

Because of the vicious attack at the Spring Ball, the Academy has decided it would be safer to build dorms for the students so they can stay on campus. The school also asks each student to bring help from home, so Melody will be going to school with Luciana! However, the school needs time to build the dorms, so our girls get an unexpected vacation - with enough time to get in all sorts of trouble!
