The anime franchise 'Shin Tennis no Oujisama' is getting further reinforcement for the upcoming story arc 'U-17 WORLD CUP – Kesshou Member Ketteisen'. As announced by the series' official Twitter account, actor and singer Yu Shirota will take on the role of Spanish national player Romeo Fernandez. This marks Shirota's first voice acting work for the anime series, after previously portraying Seigaku captain Kunimitsu Tezuka in the musical adaptations and the live-action film.
At the same time, the production team released the third teaser visual, showing the two Hyotei players Keigo Atobe and Yushi Oshitari – rivals in the internal selection battle for the final participation. The image underscores the tense premise of the new season: Before the final match against Spain, the Japanese players must compete among themselves for the coveted spots.
The music for the series has also been revealed. The opening song 'Walls And Bridges' comes from the unit 'Aozu', consisting of the characters Ryoma Echizen, Kunimitsu Tezuka, Shuichiro Oishi, and Shusuke Fuji. The ending title 'Kinkanshoku phenomenal' is performed by Keigo Atobe and Yushi Oshitari. Both pieces were composed specifically for this arc.
The new season continues the story that began in summer 2022 with 'U-17 WORLD CUP' and continued in fall 2024 with the semifinal season 'SEMIFINAL'. In 'Kesshou Member Ketteisen', it will be decided which players may represent Japan in the final against the strong Spanish team. Like the previous seasons, this one is also animated by Production I.G. A teaser video is available on the series' official YouTube channel.
Yu Shirota, who himself has a Spanish mother, expressed his excitement in a statement: 'I have previously played Kunimitsu Tezuka in the musicals, but this is my first appearance in an anime. I will do my best to convey the charm of this role and the passion of the Spanish team with my voice. Please look forward to it!'
The broadcast of 'Shin Tennis no Oujisama U-17 WORLD CUP – Kesshou Member Ketteisen' is planned for fall 2026. An exact air date has not yet been set.
