Chapter Summaries

Class B learned the island exam’s checkpoint, leader, camp, and penalty rules, then debated how to choose a discreet leader. Raku became a candidate despite rumors about him, and the class considered hiding the leader in plain sight near Ichinose.

• Teacher Hoshinomiya explained that occupying checkpoints earned points, while correctly identifying another class’s leader could shift fifty points between classes.
• Teacher Hoshinomiya outlined the camp rules, and Class B realized that supplies and other necessities would force them to spend points.
• Raku suspected that a student could secretly spend class points on purchases, making betrayal a risk.
• Ichinose led Class B’s discussion of the leader election, and Shibata and Kanzaki argued that Ichinose was too recognizable for the role.
• Class B members nominated Raku as a discreet leader, but Shibata warned that rumors about him had spread to other classes.
• Wakayama proposed choosing someone who often stayed near Ichinose to disguise the leader’s identity.

Class B organized its first steps for the island exam, choosing Shiranami as its leader and dividing students among campsite scouting, food gathering, and point planning. Raku joined Nakahara and Takashima to search southwest, and the chapter ended with the group continuing through the hot forest.

• Class B unanimously chose Shiranami as its leader and heard Teacher Hoshinomiya explain the portable toilet arrangements.

• The trio admitted they had no useful map or way to determine their direction, chose southwest, and headed into the forest.
• Raku, Nakahara, and Takashima continued through the humid forest, complaining about the heat as they searched.

Raku’s group found a hidden base with a well, and Ichinose’s class chose it as their campsite while planning how to spend their points. Soma suggested replacing the shower room with a cheaper outdoor shower, and the chapter ended with Ichinose’s group considering the idea.

• Raku, Takashima, and Nakahara pushed through the forest and discovered a marked path leading to a secluded base.
• Raku stayed behind to secure the base while Nakahara and Takashima contacted Ichinose’s group.

• Ichinose’s group chose the base, planned to wait for the well-water test, and discussed buying hammocks, a portable toilet, food, and other supplies.
• Soma proposed buying an outdoor shower instead of a shower room because it cost fewer points and could use water from the well.

Raku helped Soma and the others set up hammocks and gather food, then joined Ichinose to collect firewood. The chapter ended with Raku and Ichinose heading back to camp, where she remarked that he seemed unusually accustomed to the stifling heat.

Raku and Ichinose encountered the eccentric Koenji in the forest, where Raku answered his boastful questions with a clever insult. Back at camp, Raku checked on Ichinose after noticing she had been unwell, and Kanzaki questioned why Raku had been unusually active.

• Ichinose and Raku discussed how she could read Raku’s expression while walking through the hot forest.
• Koenji swung through the trees, introduced himself to Ichinose, and asked whether he looked beautiful on the island.

Shinomiya’s class took in Kaneda Satoru after Ryuen beat him and drove him from Class C, while Kanzaki discovered a nearby patch of ripe corn. The next section began with the class struggling to sleep on the hard ground, as Shinomiya waited to see whether the girls would accept his hammock.

• Yasuda’s food-search party brought the injured Kaneda Satoru back to camp, and Shiratori explained that Ryuen had beaten and expelled him after an argument.

• Shinomiya waited in his hammock beneath a noisy plastic waterproof cover as the class settled in for the night.

Soma Shuhei helped the girls find a way to soften the tent floor, while the class put its plan to protect leader Shiranami Chihiro into action. Later, the narrator secretly inspected Kaneda Satoru’s bag and found a digital camera before hearing someone open a zipper behind him; the chapter then shifted to an unexplained nighttime disturbance in a girls’ tent.

• The class chose Ichinose Honami to carry the special unlocking card and used teams to conceal Shiranami Chihiro’s identity as leader during occupation attempts.
• At 3:14 a.m., the narrator removed his broken tracking watch and searched Kaneda Satoru’s backpack, finding a digital camera containing only landscape photos.
• The narrator returned the camera to Kaneda’s bag, then heard a zipper open inside the girls’ tent and saw a lantern light behind him.
• A girl woke in the dark to clacking and beeping sounds, then struggled to fall back asleep in the muggy tent.

Raku accidentally frightens Ichinose outside the tent at night, learns that she is afraid of ghosts, and promises to help if she needs him. The next morning, the group gathers corn and discusses the safe well water, incoming food, and their Class Points.

After leaving Ryuen’s camp, Raku accompanied Ichinose as she scouted Class A’s cave base and learned that Katsuragi kept the class’s device inside. Back at their camp, Ichinose resumed cooperation with Horikita and Ayanokoji, while Raku worked on his hammock.

• Ryuen offered Raku cold water, but Ichinose pulled him away and angrily told him to report any trouble to her in the future.
• Raku and Ichinose found Class A’s cave base, where Katsuragi confirmed that the device was inside but refused to show it to them.
