The Unique Premise of SI-VIS

At the heart of SI-VIS is a captivating premise: the globally celebrated mixed-gender vocal unit, SI-VIS, fronted by the charismatic Yosuke.

This ingenious narrative twist sees the public viewing their extraordinary heroic skirmishes as nothing more than meticulously choreographed concert acts, creating an intriguing duality that promises both suspense and emotional depth.

The Creative Powerhouse Behind the Series

The creative powerhouse behind this innovative project includes industry luminaries. Fumiaki Maruto, renowned for his masterful storytelling in Saekano: How to Raise a Boring Girlfriend, is steering the ship as the project supervisor and scriptwriter, ensuring a compelling narrative. Complementing his vision are the distinctive original character designs by Hidari, celebrated for their artistry in works like Santa Company and Phantom in the Twilight.

Meet the Voice Cast and Musical Talent

The vocal ensemble bringing these characters to life boasts an impressive lineup of acclaimed voice actors: Daisuke Namikawa lends his voice to Yosuke, joined by Ayane Sakura as Siren, Akari Kitou as μ (Mu), Nobunaga Shimazaki as Souji, and Souma Saitou as June. In an exciting development, Sony Music has confirmed plans to meticulously select dedicated vocal artists to provide the singing voices for these roles, with announcements regarding these performers to follow.
