Allister is exceedingly introverted, shy, soft-spoken, and bashful, hence always wearing a mask to conceal his face when he's around other people. Allister is a young boy with pale skin and purple eyes. His black hair is fairly short but with a few long strands in the front and a long curved cowlick at the back. On his face is a white mask with large holes for his eyes and mouth with motifs that looks similar to Corsola's motifs on the sides. He likes to hang out in graveyards and ruins.
