HOMEWORK AND FIREWORKS
Thrown into the midst of five beautiful sisters who hate studying, Futaro must figure out how to keep them from flunking out of school. But he has to start from the beginning and earn each girl's trust first! His effort to befriend the sisters starts off rocky, but he bonds with Miku over her love of Sengoku Period warlords. It all seems for naught, though, when a bath-related mishap with Nino threatens everything Futaro's worked to accomplish! Will he be able to prove his innocence and gain their trust? Maybe a fireworks festival will brighten their moods!
