Unsure if this is Illyasviel. Just a whole host of seemingly unrelated tags, but tagging it as her for the moment. Supposedly it is one of the characters as a possible Avenger.

Kinda really wierd, the pixiv tag has both the Scáthach and Illyasviel tag in it and the title also:

イリヤスフィール.avenger（スカサハ.lily?)

=
Illyasviel avenger (scathach.lily?)

so it's a corrupted fusion?
