at first i did think this was ayu (despite the fact that i think its a guy) but he knows the dances so perfectly and he moves just like ayu and in certain lights he does look a little like ayu!! just see for yourself. His videos seem to be from like an impression night called a museum from somewhere

just found out this is part of an ayu theme night at a gay/drag bar in japan. there are some other videos on youtube
