[Machine Translation] The season is summer. After the final exam, Kiyotaka and his classmates had a two-week cruising trip on a luxury cruise ship. The students were delighted, but there was no way that the school, which is based on perfect performance, would plan a simple trip, and the ship arrived at an uninhabited island. The ship arrives at a deserted island, where the students are informed of the first special test of the school year: survival on a deserted island. Living supplies can be purchased with the points given for the test. However, the points retained until the end of the exam will be added to the students' school life from the second semester. In order to bridge the gap with the top classes, the bottom D class students plan to not use their points and embark on a life of survival, but the special exam is anything but sweet...! This is the third installment of the new school apocalypse from the popular creators!
