Mob Z Breaks the Fourth Wall

Mob Z, despite being a literal background character had the opportunity to speak the great omnipresent being that wrote the masterpiece of a world she lives in. Join her as she tsukkomi herself while the author narrates the story happening around her. And maybe, just maybe, she gets promoted to being the protagonist of her own story. [Pshhh, not gonna happen. Not with how unoriginal you are.]
