so is some Vtuber kinda thing ?

Indeed. This looks like shorts from what's probably Tusnomaki Watame's channel, possibly as some way to experiment with the model software and what they can do with it. Honestly not sure why it's here, but sometimes Gogo just uploads random stuff.

nawh not random stuff this is because the mods are probably into watame for sometime now hahahahaa im gonna get silenced byu matrix soon hahahahaha gogo mod reading this tho haha
