There's a Mugen dark reimu?

Apparently her name is "禍霊夢" according to pixiv tag.

Is she the reimu on this video, or am I wrong?

M-Reimu / 禍・霊夢 (the reading is Maga-Reimu,) is a mugen character who was created by 熄 癈人 (Oki Haito), using Magaki as a reference.
Oki said she has separated from Reimu for some reason.
