Without ever taking a bath, wearing the same underwear for a month straight, and brushing her teeth only once every three days, Aika has completely lost any sense of cleanliness, becoming a one-of-a-kind filthy schoolgirl with an intense body odor. She makes a fortune through paid encounters with older men who are attracted to her smell, while her boyfriend has been trained to obediently submit to her stench. Even her school teacher becomes entranced by her foul aroma. This is the perverted story of a degenerate slender aggressive girl from Dog / Delusion Tribe, tormenting male masochists as she utterly destroys her image as a model student.
