The production also saw a change in animation studios, with the baton passing from Telecom Animation Film to Electric Circus. Despite this shift in the production team, fans need not worry about losing the show's visual magic; key staff members such as series composer Yuko Kakihara and character designer Miho Tanino—have been retained to ensure continuity with the visual aesthetic established in the first season.
Accessing the continuation of Taiki’s journey in the badminton club—as he strives to catch up with Chinatsu, a star in the basketball club—is incredibly easy. For fans in Indonesia and across the globe, the streaming giant Netflix serves as the official broadcaster.
Fans can watch new episodes, updated every Sunday, complete with Indonesian subtitles. Additionally, the anime-focused streaming service Crunchyroll is simulcasting the series to reach international audiences worldwide.
Overall, the release of this creditless video sets the perfect stage for Blue Box Season 2. With a blend of visually stunning direction by Electric Circus, a magical song by aiko, and escalating romantic and athletic tension, the second season is poised to become one of the most popular anime of the Fall 2026 season.
