Aniplex and Sony Music have officially announced that the original TV anime SI-VIS: The Sound of Heroes will begin airing in October 2025. The project, which was previously teased as a “MUSIC × HERO” anime through a countdown website launched on July 24, has now unveiled its cast, staff, teaser visual, and promotional video.
The story will follow SI-VIS, a mixed-gender vocal unit that’s famous worldwide. However, they are actually also heroes fighting against a mysterious disaster that threatens humanity. Their live concerts double as battles, where the energy of the crowd becomes their strength, while the public believes they are simply entertainers.
The main cast includes:
- Yosuke (Leader): Daisuke Namikawa
- Siren: Ayane Sakura
- μ (Myu): Akari Kito
- Soji: Nobunaga Shimazaki
- June: Soma Saito
