The Prince of Tennis II is pushing its U-17 World Cup arc into its next stage: the newly announced Kesshou Member Ketteisen (final-member decider) has revealed additional cast, new staff, a key visual and its first promotional video, with a premiere set for late September into October 2026. It's the continuation fans of the U-17 World Cup run have been tracking since the Semifinal.
The new cast
Per the official reveal, the decider chapter adds voices for Spain's team, including Tasuku Hatanaka, Reiji Kawashima, Ryuuho Nagaoka and Megumi Han. The staff and studio continue the U-17 World Cup production line that carried the 2022 series and the 2024 Semifinal.
The promo video
Where it sits in the arc
This is squarely a continuation, not an entry point. New Prince of Tennis (Shin Tennis no Ouji-sama) built to the U-17 World Cup, the 2022 TV series and 2024 Semifinal advanced it, and the Ketteisen chapter is the next bracket. If you're new, this is not the place to start — the earlier series are.
The ranking note
SenpaiRanks tracks the U-17 World Cup TV series in the mid-tier of its sports-anime board, a niche-but-durable franchise with a committed fanbase rather than a breakout hit. The dual-axis read is honest here: it plays best for viewers already invested in the Seigaku-to-U-17 pipeline.
