SI-VIS is a co-ed music group led by Yosuke, shaking up the global music scene with their unmatched vocals and performances.
They are actually heroes in disguise, however, battling against a mysterious force threatening to destroy the world. They gather energy through live performances and convert audience energy into combat power. The battles appear to be ordinary concerts to the public, so their identity remains a secret.
