Syougo Kinugasa: 3 books

Students of the prestigious Tokyo Metropolitan Advanced Nurturing High School are given remarkable freedom--if they can win, barter, or save enough points to work their way up the ranks! Ayanokoji Kiyotaka has landed at the bottom in the scorned Class D, where he meets Horikita Suzune, who’s determined...

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.
