With SFIA in the rearview mirror, Hiroto finds himself facing an even thornier problem: The next interschool event, called the Fortissimo, is played among second-year students from every ward. Of the Eimei sophomores, it's only Hiroto, the (fake) strongest in the Academy, and Himeji who've put up any real results so far, leaving the two of them all alone to take on Saionji and Fujishiro from Ohga School, as well as the newly formed alliance between Minami and Kururugi. The Game takes place on the world-famous "Casino Island," and Hiroto sees an opportunity to debut his cheats on the world stage...but he soon comes across a "completely normal teenage girl" who puts all his lies in serious jeopardy!
