Isaac

This is Isaac.

 A demon of paint and insanity.  

On their right, a side of feminine. To their left, a side of masculine. 

Two sides, two personalities. 

Tho both sides are of their own personality, each thrives on one goal. To torment, to deceive, and to murder. 

That's basically what I got right now XD 

P.S. They have shapes in their eyes.
