Cosplayer むー or むぎ (translated as Mumu or Mugi) posted photos on Twitter of her Krystal cosplay a few days ago. The costume appears to be a furred zentai suit with sewed in tattoos. She appears to be using a facial prosthetic for the muzzle, like Kat the Leopardess did long ago. Custom clothing, jewelry, armor, a wig, ears, and a staff complete the costume. I can't tell if this cosplay includes a tail. I'm messaging the cosplayer for more information and photos.
Photos were taken by LL_Spider3. Thanks to Ayano for bringing this to my attention.
