They are neither Hololive or Vshojo material and they know what Niji is, and they're either too small or mentally unstable to make it as indies. Phase is all they have. Sakana also seems to be a pretty nice guy who gives them a lot more freedom when compared to other corpo CEO's. As long as they do original songs and covers from time to time, he doesn't seem to care what they really do otherwise. In short, it's a golden ticket for them. And although it doesn't make them millionaires, at least they get paid for doing what they were already doing before, that is, playing vidya and shitposting.
