SI-VIS is a Japanese music group best known for its connection to the original TV anime SI-VIS: The Sound of Heroes. The project entered anime music coverage through promotional material that introduced the insert song “MELODEA,” along with a first-cour trailer and key visual.
The anime was announced to run for two consecutive cours and premiered in October 2025, later adding a second-cour trailer and visual as well as creditless opening and ending videos. That association gives SI-VIS a clear place in recent anime and anison-related search interest.
