Omegaα (Omega alpha) is a member of hololive production. They were introduced through a short PV and a slide with information during the post-debut collaboration of the hololive English -Council- members. Shortly afterwards, the PV, titled The Advent of Omega was uploaded to the official Hololive English channel.
Their relation to the members of Hololive English is currently unknown, only that they have a similar position to A-chan's.
Omegaα's first mention was in the credits for IRyS's Caesura of Despair MV, with Omegaα listed as the video's Producer.
Although they've became known only after the debut of hololive English -Council-, Omegaα has been working behind the scenes with Hololive English since it started as the first staff of the EN branch.
