Original TV anime jointly produced by Aniplex and Sony Music.

The upcoming TV anime SI-VIS: The Sound of Heroes has been confirmed to air for two consecutive cours starting on October 5. Alongside the broadcast details, the opening and ending theme songs for the first cour have also been revealed. The series will be available for streaming on Crunchyroll.

The opening theme is “So Far Away”, while the ending theme is “FRIENDS & SMILE.” Both tracks are written and composed by Takui Nakajima and performed by the in-anime band SI-VIS, continuing the franchise’s approach of tying the music directly to the story.
