One day, they get a new student teacher who happens to be De Metorio royalty, Princess Yurikano. She runs things a lot differently than Izo and the others are used to, but there's more to this princess than meets the eye. Will Yurikano be able to get Izo and the others to accept her training, and will she be able to survive the enemies that are gathering against her?
