Unveiling the World of “SI-VIS: The Sound of Heroes”
“SI-VIS: The Sound of Heroes” introduces a unique premise where a co-ed music group, wildly popular globally, secretly operates as heroes. They battle mysterious forces threatening the world, converting the energy generated from their live performances into combat power. To the public, these battles appear as ordinary concerts, keeping their heroic identities a secret. The series aims to blend the vibrant world of idol anime with superhero action, offering a fresh take on both genres.
The Plot and Premise
The story centers around the SI-VIS vocal unit, whose members gain the power to fight against a looming calamity through their music. Kyōya, a young man from Aomori, harbors a desperate desire to join SI-VIS, especially since the group’s leader, Yosuke, is his cousin. The first episode notably features a live concert in Shibuya with over 100,000 attendees, setting the stage for the group’s musical and heroic endeavors. While Kyōya possesses potential, the narrative positions him as an eager individual who initially gets ahead of himself, requiring training and skill development beyond just his connection to the leader.

Daisuke Yoshida is directing the series, with Fumiaki Maruto handling the series composition and script.
