An unforgettable summer begins. 頼伸 NARITA (Rai), a second year high school student who is the president of the Quiz Society and has only two members, is called "Nainaka" in the class because he has the same family name as Rai and a popular member of the dance club, Kiyoharu NARITA (Kiyo). Speaking of "Narita-kun" in the class, Rai means Kiyo. Rai likes "not being useful" and Kiyo likes "being useful" with an emphasis on efficiency in preparing for university entrance exams.
