Artist's commentary
Basically this is supposed to be a bodied Rika(pc 98 character) yukkuri who went insane because of her uneasy life. Her clothes are a discarded jacket and a long tattered shirt (she has no undies as she never ever felt the need for one because she is a yukkuri, duh). The weird red hat is her accessory.
She is supposed to be eating garbage >_>
I will add in the details and the comment story in a later upload as I have things to do.
