I’ve seen this model, and not just from one creator but from several. From what I noticed, there isn’t much difference between their versions in the videos. They say the model is by TararaTarako, but after looking into it, I realized that he didn’t actually create this model.
They used a body by TararaTarako (I don’t know which model the body was originally taken from), while the head and clothing are most likely from Cover Corp (Moona Hoshinova).

I’ll send you the creators of the two videos that used this character model. But if you search around online, you can find even more videos featuring similar characters with models that look very close to theirs.

These creators also have R18+/NSFW videos using the same model. If anyone knows where it can be downloaded, or if someone has the model and is willing to share or trade it, I’d really appreciate it.
