The story centers around Kanade Amakusa, a boy cursed with the mental power of "absolute multiple-choice" — a multiple-choice quiz will suddenly appear in his mind, and the choice he makes will become his reality. For example, he would have to choose between going nude from the waist up and screaming like true japanese man or the waist down in school and screaming like amazon warrior. While in school, he is given another choice: 1) A beautiful girl will fall before him or 2) Gondo daiko-san will fall before him. He chooses option 1, and a blonde girl named Chocolat falls before him.
