The story follows Io, a young boy troubled by his profane and arguably perverted thoughts - creating a lot of difficulty when it comes to talking with girls. His relationship with his confedant and only real friend, a monster girl, creates some tension when the world starts experiencing natural disasaters and hostility from the other monster girls!
With rumors of a "Legendary Monster Girl" bent on world destruction starts to circulate, mankind is forced to take a stand. Io must now investiage the origins of the occuring phenomenons, taking his childhood monster girl friend along with him on his adventure into the world of monsters.
