The second season of Blue Box will have its broadcast premiere during the Fall 2026 anime season. A snowy “blue visual” with footprints heading in the opposite direction was also released.
The teen romance anime is based on the manga by Koji Miura, which Viz Media describes as such:
Taiki admires Chinatsu from afar, but he doubts that she sees him in the same way. Yet somehow, he musters up the courage to tell her to never give up on her dreams! After such a bold declaration, will Taiki’s fleeting high school romance finally begin?
The manga began serialization in 2021 in Shueisha’s Weekly Shonen Jump and has 23 volumes as of December 2025. It was originally a 2020 one-shot.
Season 1 had its premiere on October 3, 2024 and ran for two cours.
