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! For summer break, the first-years are sent on a luxury cruise to a remote tropical island. And as the students learn, it\'s yet another of the school\'s bizarre tests. All four classes will spend a week competing against each other for resources, and the results could drastically change their rankings. Class D has nothing to lose and everything to gain, but if they want to win, they\'ll have to work together-and stay one step ahead of their opportunistic rivals! (W) Syougo Kinugasa (A) Yuyu Ichino
