It's already been either IronLung, or Filian, or [insert large twitch indie here] for years if you ask most EN-only vtuber watchers. They both get great numbers and every twitch retard who came within simping distance of a vtuber knows about them.
The best part of it all is that they'll never be able to admit that the most accomplished EN vtuber out there, by fucking far, is Mori.
