Sora is a childhood friend who has lived in the same neighborhood since we were kids and we've been good friends ever since.

One day, I was asked by Takemaru-senpai, the craziest delinquent in my hometown, to go and sell some party tickets. Sora, who has always been competitive and righteous, said, "What is that? I can't forgive that!" and said she was going to protest...!
