This is a song from (or possibly just about? not sure) a 1920s-cartoons-themed survival horror game called Bendy and the Ink Machine. I don't know a lot more than that about it, but I would just like to note that it's a hella catchy song, and that this particular Miku model is super cute for a dæmoniacal incarnation of vengeful evil. (This is almost certainly one of Koemi Takata's favorite modules.)

Also, as noted in a comment I made on the YouTube page itself, I can't get over how expressive she is. MMD has really come along.

OK, she's not actually singing, which a number of the commenters can't seem to get past, but having attempted it myself, I can say with confidence that Vocaloid is hard, man. I can't blame the person who made the video for deciding that just doing the MMD part was enough work.
