Ayanokouji's relationship with Karuizawa deepens, while the aftershock of his perfect mathematics score ripples through the school. Horikita asks to join the student council, and is accepted by Nagumo. And summer vacation brings with it no rest, but another special exam--a reprise of the earlier deserted island test. Except this time, it'll be a battle royale with all three grade levels duking it out against each other!

As Ayanokouji and his classmates begin their second year at the Advanced Nurturing High School, they're greeted by a fresh gauntlet of exams and a fresh batch of rather unique first-year students. They'll have to get to know each other quickly, because the first special exam pairs the first-years with the second-years on a written test--with only the second-years facing expulsion if their team performs poorly! Worse yet? It seems one of the new first-years is also from the White Room. Can Ayanokouji avoid expulsion while sussing out the identity of this hidden foe?

The second half of the special summer test finds the students duking it out aboard a luxurious cruise ship. Divided into 12 groups patterned after the signs of the Zodiac, all four classes are faced with a devilishly difficult test of their thinking skills. They may have survived the island, but they're not out of hot water yet!

Having survived their final exams, Ayanokoji and the others are looking forward to an idyllic school-sponsored summer vacation aboard a cruise ship. But nothing is ever quite as it seems with the Tokyo Advanced Nurturing High School, and the cruise turns out to be the cover for a series of special tests! What grueling new challenges await them out at sea?!

Class D has conquered the midterms, but their celebration is cut short when three Class C students falsely accuse Sudou of assaulting them! With their friend facing expulsion, and the class’s points on the line, Ayanokoji, Horikita, and Kikyou must team up to gather evidence to prove his innocence.
