Infinite Ryvius (Japanese: 無限のリヴァイアス, Hepburn: Mugen no Rivaiasu) is a 26-episode science fiction drama anime series produced by Sunrise.

The series is noted for its music, which blends Western R&B/hip-hop with J-pop vocals, including its title song "dis–", performed by bilingual Japanese-American singer Mika Arisaka.

Following the closure of Bandai Entertainment, Sunrise announced at Otakon 2013 that Sentai Filmworks had rescued Infinite Ryvius, along with a handful of other former BEI titles.

The Liebe Delta begins free falling into the depths of the Geduld Sea, where the intense gravitational pressures threaten to crush the station and kill everyone aboard.

Just as the station teeters on the edge of collapse, a hidden ship called the RYVIUS activates and surfaces from the Geduld Sea, rescuing the surviving students aboard the Liebe Delta.

He faces personal challenges (including clashes with his brother Yuki), his complicated feelings for the Uranian aristocrat Fina S. Shinozaki, the task of avoiding Aoi, and the mysterious appearance of a girl in pink wandering the halls.

The Vaia ships are said to be crucial to mankind's survival, despite their effect on those exposed to them for long enough, which results in a major mental breakdown as seen with the Blue Impulse's captain after losing the battle with the Ryvius.

After an intensely fierce battle and the loss of his Vital Guarder, Conrad Vicuss took his own life, marking the end of the war between the Orbital Security Bureau and the crew of the Ryvius.
