At the beginning of this chapter, we are introduced to a new character named "peak hina" , who tells us that she and her sister, "yukina," are in a rock band together. She tells us she is tired of being compared with her older sister, and that she wants to be a part of the band, even if she does not want to be in it herself. She also tells us about the fact that she has started a band with another drummer, "lisa nee," who is also a member of the same band as her sister.
