The voice actors actually sing. Not as themselves, as the characters you watched compete on court, now plugged into a full rock concert where every player gets a moment that feels earned. It's fan service that knows exactly what it's celebrating: not the tennis, but the voices that made you care about the tennis in the first place. A single episode that exists purely to let the cast have fun, no plot getting in the way. If you spent years with these characters, this is what closure looks like, them alive, performing, still themselves.

Most of the Prince of Tennis cast step away from the court and appear as a band in this single music video, which plays out like a concert intercut with flashbacks. Tezuka comes back to Japan after rehabilitation in Germany, rejoining his bandmates as Aozu and Cap to Bin prepare a joint show, and all nine vow to make it their best. The two songs, Birthday and Rock 54, are sung by the original Seigaku voice cast.
