The evil Queen Gessurian could not tolerate the existence of anyone more beautiful and powerful than herself, and thus plotted to torment the heroic heroine Magna Pink, Momoshima Makoto, aiming to strip her of her beauty. As part of her scheme, she allied with the toothbrush monster Habrashilla, disguising themselves among humans to spread cavity bacteria among those with beautiful teeth, grotesquely ruining their faces. Momoshima Makoto infiltrates a dental clinic where strange rumors have begun to circulate, attempting to expose their true identities—yet the moment she uncovers the true forms of Queen Gessurian and Habrashilla, the story takes a tragic turn.
