is a 26 episode drama/sci-fi series produced by Sunrise. The character and mecha designs in RYVIUS were created by Hisashi Hirai, who later went on to act as the character designer for Gundam SEED. The series is also noted for its music, a blend of western R&B/hip-hop music with J-pop vocals. This is evident in the opening song, "dis–", performed by bilingual Japanese-American singer Mika Arisaka. Most of the vocal songs were composed by M.I.D. and the thematic background instrumentals by Katsuhisa Hattori. The anime was originally licensed by Bandai Entertainment in North America before it ended up going out of print in 2012. Following the 2012 closure of Bandai Entertainment, Sunrise announced at Otakon 2013, that Sentai Filmworks has rescued Infinite Ryvius, along with a handful of other former BEI titles. A two volume manga adaptation was released concurrently with the series in 1999-2000, and was then published in English in 2004. A parody spin-off original net animation (ONA) series, Infinite Ryvius: Illusion, was released in 2000.

Stretching from the sun to the edge of the solar system, this area of high temperatures and gravity pressures has never been explained. Kouji Aiba is a sixteen-year-old boy who packed his bags and left his home on Earth for the Liebe Delta and the training to obtain his Level 2 piloting license. He journeys to the space station accompanied by his childhood friend, Aoi Housen, whom Kouji discovers to his chagrin has enrolled in the Liebe Delta's flight attendant program. En route to the spaceport Aoi gives Kouji the additional unwelcome news that his younger brother, Yuki, is also to attend the Liebe Delta and in fact the brothers will be in the same flight class together. The list of Aoi's unfortunate news to Kouji is
