99% sure this is a high effort shitpost rather than a low effort honest endeavor. Hits the same vibes as Nyan~ Neko Sugar Girls or Large Bagel.
Also Nyanners (who allegedly had a hand in Large Bagel, coincidentally) watched the trailer on stream, with chat shitting on it
and they retweeted it.
We need more silly content that pokes fun at vtubing, so I'm going to watch the whole debut thing if it happens.
