From three stars in volumes 7 and 8 to a five-star rating in this volume, what an improvement! It was well worth continuing the story. In this light novel the main focus was the Irido siblings and of course they're best friends. In previous reviews I griped about the boring and bland student council members, thankfully in this volume they're not mentioned too often. The author has gotten better at building characters in this volume and connecting points whereas volumes 7 and 8 had too many characters introduced too quickly. It should be noted that this volume does contain sexual content #no spoilers
