After the defeat of Aizen, Ichigo has lost his superpowers but not his skills so he's been hiring himself out to any sports team looking for a strong player. When Nagisa Hazuki approaches Ichigo to join the Iwatobi High School Swimming Club, something piques Ichigo's interest....

The one in which Tsuna and his friends consciously disperse to the four winds when they reach high school, and somehow, all of Tsuna's classmates manage to fall desperately for him before the end of their first year together. And have to find some way to deal with it, since life doesn't stop just because the most unremarkable guy in their year seemed to become irresistible overnight. The most popular defense in their arsenal? Is the phrase, "Sawada Tsunayoshi? Makes. No. Sense." (Or: All Tachibana Ren had wanted was to make a place for himself, away from Iwatobi and the protective hovering of his family. Nothing could have prepared him or the rest of his class for what getting through high school alongside one Sawada Tsunayoshi would mean for them in the long run.)
