SI VIS: The Sound of Heroes is the newest original anime making waves in the lead-up to its October 2025 premiere. A collaboration between Aniplex and Sony Music, the series blends music and heroism in a world where live performances are more than entertainment they are battles for survival.
First teased through a countdown website earlier this July, the full reveal brings a rich combination of music, action, and stunning visuals. SI VIS follows a globally popular vocal unit made up of five members who, while adored as musicians, secretly act as heroes in a fight against a looming mysterious catastrophe. Each live concert becomes a battlefield, drawing energy from the audience to fight invisible threats. What looks like a dazzling stage performance hides a deeper, more dangerous mission, one the public remains completely unaware of.
The vocal unit includes Yosuke, voiced by Daisuke Namikawa, who serves as the group’s calm and determined leader. Siren is brought to life by Ayane Sakura, while the enigmatic μ is voiced by Akari Kito. The stoic Soji is portrayed by Nobunaga Shimazaki, and the energetic June is played by Soma Saito. Together, they bring a strong mix of chemistry and charisma, essential to both the music and the story’s dramatic core.
While details on the actual singers behind the music remain under wraps, Sony Music has confirmed that some of its top vocal talents will be performing the songs for the series. These will add emotional depth and intensity to the already high-stakes story.
Behind the scenes, the anime boasts an impressive creative team. Fumiaki Maruto, known for Saekano: How to Raise a Boring Girlfriend, is handling the series composition and script. The character designs come from renowned illustrator Hidari, who has previously worked on projects like The Magnificent Kotobuki and the Fire Emblem game series. Hidari is also responsible for the first teaser visual, which captures the blend of stage glamor and looming danger that defines SI VIS.
As the teaser trailer shows quick flashes of stylish animation, glowing stage lights, and a heroic aura around the main cast, it becomes clear that SI VIS is shaping up to be a genre-bending experience. It is not just an idol anime and not just a superhero story it is a fusion of both, with a fresh approach that appeals to fans of high-concept narratives and emotional drama.
With its October launch drawing near, SI VIS: The Sound of Heroes is one of the most anticipated new titles in the anime world this year. Combining the energy of live performance with the intensity of combat, this original story promises a powerful and emotional ride for anyone watching.
