Yamada no Ero-gami

Is "Yamada's personal deity", who aids her towards her goals (although she cannot be seen or heard by anyone) and represents her "pervert side". She takes on the appearance of a super deformed version of Yamada, save the mustache, and floats around on a pink cloud. This character also acts as a narrator at times recapping past events as well as occasionally breaking the fourth wall to address the audience.
