Nijiura Maids tag doesn't belong here, you're mistaking Nijiura Maids with Maidcore.

The artist tagged it "Nijiura" and the scythe_of_luna tag on Pixiv has art of this character with yakui_(nijiura_maids) so I'm fairly certain they're related in some way, but I'll throw a check copyright on it.

Edit: Oh, some sort of musical project?

Nijiura Maids were maid characters created on Futaba Channel by anonymous japanese users in the 2000's and early 2010's, Scythe of the Luna is the original character of an artist with ties to Maidcore, which is a Russian musical community where artists sometimes make use of the Nijiura Maids as part of their identity (with Yakui being one of the more popular artists), they are two different communities, with one being based on the other, so the Pixiv tag is also wrong unfortunately.
