Seitokai no Ichizon
The members of the student council of Hekiyou Academy are chosen by a popularity vote. As a result, all the members are cute girls except for Sugizaki Ken, who studied hard to enter the council. This novel is about the endless chatters of the members, full of parodies from various other works such as "The Melancholy of Haruhi Suzumiya," "Dragon Ball" etc. (Source: MyAnimeList)
