Ultraman Nexus aired in 2004 as part of the Ultra N Project, an attempt to revamp the Ultra Series. Nexus was notable for its darker tone, and for using multiple hosts, known as Dunamists. The show was cut short to 37 episodes because its tone didn’t sit well with younger fans, so the ratings suffered. Later, the show was re-aired in a late-night slot with better ratings.
In the description of the video, they revealed that Nexus would be their latest show to stream on Crunchyroll, joining Leo, 80, Max, Mebius, and the currently airing X. Tsuburaya did not specify when Nexus would be uploaded.
