ようこそ実力至上主義の教室へ　４ [Youkoso Jitsuryoku Shijou Shugi no Kyoushitsu e (Manga) 4]

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!
