A-chan is a production manager that became a spokesperson ad hoc when the company was so small that it had to grab a random staff member to run PR.
Omega was the brand manager of the EN branch, meaning he was the highest level in charge of everything related to the EN side of the business. Every talent manager answered to him, EN production managers would have answered to him (except he never hired any, oops) and all aspects of the marketing and event coordination for ENs, including their involvement in JP events, were overseen by him. He is in some way responsible for everything involving the EN branch for the period where he was in the company. Perm issues? Omega. Talent managers issues? Omega. "Sorry we can't participate in this jp event that we were very publicly invited to by jp talents... it's complicated" Omega.
IRyS live2d model? Approved personally by Omega.
Council's weird ESL chuuni lore videos? Commissioned and written by Omega.
And yes, in case it wasn't obvious, them naming themselves AlphaOmega and commissioning their own live2d avatar with misappropriated company funds and then hijacking Council's debut collab to promote themselves was entirely a self-motivated ego project taking advantage of the fact that the main hololive office didn't have enough english-speakers at the time to provide proper oversight.
