Whos this asian cosplayer?

Girl who for some reason, doesnt exist on any known search reverse image engine, passed essentially every prominent frame in the sample video through reverse image search engines like yandex and google and got nothing. Shes more off the grid than most international spies atp. Any help or even a tiny lead would be amazing.

Only thing I got from Google was this: and this which looks like a korean board where the exact same question was asked but it requires age verification through a korean service which I cant do.

Otherwise the original source was ripped from here: at 0:30

But I couldnt turn up anything useful from the original source or anywhere else
