This is just fanart done by Dion Rogers, she/he, I have no idea what it is, anyho it was done for a contest. Here's the artsite where she has the works.

I'm not sure if it's up and ready, the last time I've checked it was down. However, this fanart is getting quite popular in cosplay along with the Amano Rinoas! XD
