As the second semester begins, two additional events are announced: the school's sports festival and its first-ever cultural festival! But before these two can kick off, an unexpected special exam will be held. The rules seem simple, but the questions might be heavier than anyone expects... Are the students truly ready to cast their final votes?

The exam is over and the students' summer break has started aboard a luxury cruise ship! Unfortunately, it's not all fun in the sun. Ryuuen is on the hunt for the person that attacked Kinoshita and Komiya on the island, and for some reason, the entire third-year class seems to be watching Ayanokouji very, very closely... Can everyone enjoy their vacation despite the rough waters ahead?

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.

The results of the Unanimous Special Exam weigh heavily on Ayanokouji's class. Kushida, Hasebe, and Wang haven't come to school in days. But time marches on, and when details of the Sports Festival are announced, Horikata's opponents disrupt the planning meeting. The class is now behind before the games can even begin! Can everyone live with the choices they've made and come out on top?

TROUBLE ON THE ISLAND 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!

NEW KIDS ON THE BLOCK 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?

I KNOW WHAT YOU DID THIS SUMMER The grueling summer vacation special tests are finally at an end. As the clock ticks down on the last glorious days of summer, the students of the Tokyo Metropolitan Advanced Nurturing High School frantically try to squeeze in all the things they’ve left undone and unsaid. Get a glimpse into the secret lives of supporting characters and watch romantic confessions and pool-side drama unfold in this volume of short stories that bridges crucial gaps between the end of first semester—and the start of the second.
