Is this an animation produced from a game? If so, what game?

Yep love the huge number of MMD videos some fantastic some bad and all in between. My favorite are the group of girls totally nude shaved dancing a coordinated dance where each girl has some way to seam like a human not a robot in the number. But there are hair and strip videos too, sex ones with mmd normally not that good as it is way to easy to put a arm or leg inside the people to edit so they tend not not movie much, but there are a few great ones.
