The story centers on a wildly popular co-ed vocal group known as SI-VIS. While they're famous worldwide for their music, they're hiding a massive secret: they are actually a team of heroes who fight against a mysterious threat trying to destroy the world. The coolest part? They gather the power to fight through their electrifying live performances!

The project is backed by some serious A-list talent. The story and scripts are being handled by Fumiaki Maruto, the original creator of the beloved series Saekano: How to Raise a Boring Girlfriend.

The show also features an all-star voice cast, including:

• Ayane Sakura as Siren

• Sōma Saitō as JUNE

• Daisuke Namikawa as YOSUKE

• Nobunaga Shimazaki as Sōji

• Akari Kitō as μ (Myu)
