Melancholy, unmotivated Kiyotaka Ayanokouji attends his first day at Tokyo Metropoiltan Advanced Nurturing High School, a government-established institution for training a generation of Japan's best and brightest. In this school, it is said, everything is decided based on merit, which includes the generous monthly "point" allowance students can spend at local shops. As Ayanokouji begins navigating this system, he also nurtures curious relationships with aloof fellow outsider Suzune Horikita and the terminally gregarious Kikyou Kushida.

As part of a special test, the school has brought the students to an uninhabited tropical island where they must now live for a week. Their performance on the test can have an enormous impact on the point standings of the four classes.

Ayanokoji's class embarks on their first trial as the ascended Class C, the mixed training camp.

While Class C are discussing Karuizawa and Hirata's break up Yamauchi is approached by Sakayanagi from Class A. Horikita warns that it's a trap, but Yamauchi pays it no heed. Meanwhile, Horikita tells Ayanokoji that rumors are swirling around Ichinose.

Turns out the one spreading the rumors was Hashimoto, who did so at the behest of Sakayanagi. Shortly thereafter, Sakayanagi appears before Class C and she informs them she has evidence regarding the rumors about Ichinose.
