The Prince of Tennis II: U-17 World Cup Kesshō Member Ketteisen is gearing up for its fall debut, with the production team unveiling a third teaser visual and key details regarding the show's musical identity. The series, which follows the high-stakes drama of the U-17 World Cup Semifinal arc, will focus on the grueling selection process to determine Japan's roster for the final showdown against Spain.

Musical talent for the new season features a mix of familiar voices. The opening theme, "Walls And Bridges," will be performed by the unit Aosu, consisting of Junko Minagawa (Ryōma Echizen), Ryōtarō Okiayu (Kunimitsu Tezuka), Yuki Kaida (Syusuke Fuji), and Takayuki Kondō (Shuichiro Ōishi). The ending theme, "Kinkanshoku phenomenal," features a duet between Junichi Suwabe (Keigo Atobe) and Hidenobu Kiuchi (Yūshi Oshitari).

The cast list also grows with the introduction of Romeo Fernandez, a member of the Spanish team. The character will be voiced by Yū Shirota, a film actor who previously portrayed Kunimitsu Tezuka in the franchise's live-action film adaptation. This addition adds another layer of star power to the intense international competition depicted in the series.

This upcoming installment continues the momentum of the modern The Prince of Tennis era, which saw the franchise return to television in 2022 after a decade-long hiatus. Produced by M.S.C and Studio KAI, the series has successfully transitioned from the Genius10 era into the global tournament stage. With series creator Takeshi Konomi planning to conclude the long-running The New Prince of Tennis manga serialization soon, these anime adaptations serve as a vital culmination of the legendary sports saga.
