Que es sunset en este dibujo vampira demonio o elfa oscura

Those are some massive ears, but her attire looks mighty fine thouhgh

She’s a little extra padding and a Hime-sama Laugh away from Naga The Serpent.

Sunset : Do you remember when we first met?  
Twilight : I thought I had wandered into a dream.  
Sunset : Long years have passed. You did not have the cares you carry now. Do you remember what I told you?  
Twilight : You said you’d bind yourself to me, forsaking the immortal life of your people.  
Sunset : And to that I hold. I would rather share one lifetime with you than face all the ages of this world alone.  
[hands her the geode]  
Sunset : I choose a mortal life.  
Twilight : You cannot give me this.  
Sunset : It is mine to give to whom I will. Like my heart.

Dang, that’s stylish!
