Tutor X Prince of Tennis: Tomoka

While in Italy on a certain errand, Pengxiang meets the Katekyo Hitman Reborn! cast and begins a life of watching all kinds of pairings.

R University gives the Reborn! cast a break, so they return to Japan to study at Tokyo University.

All the princes are at Tokyo University, along with the three club presidents: Tezuka Kunimitsu, Yukimura Seiichi, and Atobe Keigo.

In The Prince of Tennis, everyone except the villains and the older characters is in the tennis club.
