The latest story arc begins: Chapter 171, the summer study camp!
Tomoko Kuroki has decided to spend the summer of her last year in high school with a grueling study schedule, preparing for college, instead of just lazing around as usual. Meanwhile, Yuu-chan discovered that Tomoko's college entrance requirements allow her a window of opportunity, so she's trying her best though badly stressed out from the work.
Also at the summer camp is "Mama" Asuka (concerned that Tomoko is still lagging), and the weirdly obsessed Emiri Ucchi, who jumped at the opportunity to be with Tomoko again without even knowing what the camp was for. Ping pong?
