SI-VIS: The Sound of Heroes

Kyoya Minami, a country boy from Aomori, dreams of joining SI-VIS, the co-ed music group led by his cousin Yosuke Shiba that is shaking up the global music scene with its vocals and performances. Behind the stage, the members are heroes in disguise, fighting mysterious forces that threaten the world. Their live shows are the weapon: SI-VIS converts the audience's energy into combat power, and to the public the battles look like ordinary concerts, keeping the heroes' identities secret.
