Oreki listened as the teachers explained the Uninhabited Island exam’s rules, supplies, and point penalties. The exam was about to begin, with Class A already losing points because Sakayanagi had withdrawn.

• Teacher Majima announced that the students would spend a week surviving on the island as part of a group-cooperation exam.
• Teacher Majima explained that each class received 300 Points to spend on supplies, which could become class evaluation points if left unspent.
• Teacher Majima listed penalties for illness, injuries, rule-breaking, property damage, and missing roll call; Horikita Suzune appeared relieved that she was healthy enough to participate.
• Class A realized Sakayanagi’s absence had already cost them 30 Points, and Oreki noticed his classmates, including Katsuragi, looking to him.
• Teacher Majima said the homeroom teachers would explain bonus-point rules before the students disembarked in fifteen minutes.

Teacher Majima explained the special exam’s bonus-point rules, and Oreki proposed that Class A protect its points while negotiating with Class D. In Class D, Kōenji revealed that he had mapped forty bases and offered to become the class leader, leaving his classmates excited by the points they might earn.

• Teacher Majima explained that classes could earn points by occupying bases, but risked losing points if their leaders were identified or rules were broken.
• Oreki told Katsuragi that Class A could preserve its remaining 270 points and suggested buying Class D’s information about the bases.
• Oreki, Hashimoto, Kamuro, Katsuragi, and Totsuka Yahiko went to negotiate with Class D.
• Kōenji volunteered to lead Class D and showed his classmates photos proving that he had found forty bases and their Card Readers.
• Class D’s students calculated that Kōenji’s knowledge could let them earn up to 720 bonus points from base swipes.

Kōenji secured a Leader Card and proposed keeping most of the stronghold rewards for himself and Horikita, claiming the plan would help Class D rise. The classmates challenged his division, while Ayanokouji suspected Kōenji had secretly visited the Deserted Island to photograph the strongholds.

• Hirata realized Kōenji’s actions would not be treated as cheating, and Chabashira obtained a Leader Card bearing Kōenji’s name.
• Kōenji announced that he aimed to earn 600 Points, keep 200, give Horikita 300, and distribute the remaining 100 among the class.
• Kushida questioned Horikita about the arrangement, and Horikita confirmed it while arguing that the plan could raise Class D’s evaluation points.
• Hirata worried that the class would reject Kōenji’s proposed division, but Kōenji insisted the points were his to allocate and challenged anyone else to swim to the island for stronghold information.
• Yamauchi pushed Ike to volunteer, and Ike redirected the question to Ayanokouji, who stayed silent and suspected Kōenji had visited the Deserted Island the previous night to take photos.

Class D agreed to Kōenji's terms for capturing bases and made a long-term supply exchange with Class A. As Oreki explained how students could withdraw from the exam, Chabashira realized someone was steering Class D into giving up its Points, while Class C began grappling with the leader and guessing rules.

• Oreki offered to buy Kōenji's information on forty bases for two million Points, but Kōenji demanded five million; Class D instead accepted his terms to share the reward Points if he earned them.
• Class D agreed to provide Class A with supplies in exchange for 200 class evaluation Points each month until graduation, and Kōenji agreed to sell Class A information on five bases.
• Oreki told Class D that students could withdraw without driving their basic Points below zero, prompting some students to consider staying on the cruise ship.
• Chabashira suspected Kōenji was helping someone exploit Class D and believed Kōenji wanted to collect enough Points to leave with twenty million.
• Class C discussed choosing a leader and learned that correctly guessing another class's leader could erase that class's base reward Points and earn a 50-Point bonus.

Ryuuen planned to sell Class C’s exam supply points to Class B for private points and persuaded his classmates that the deal could fund their living expenses. He approached Class B with a story about his goal of reaching Class A and his losses to Houtarou Oreki, while Class B remained wary of him.

• Ryuuen proposed selling 200 of Class C’s 300 base points to Class B and said some students could then withdraw from the exam and return to the cruise ship.
• Class C’s students grew enthusiastic when Ryuuen promised the sale would provide each of them with 20,000 points in living expenses by graduation.
• Ryuuen entered Class B’s gathering, where Ichinose challenged him over his treatment of Ibuki and Kanzaki questioned his claim that he had come to throw in the towel.
• Ryuuen explained that he wanted to reach Class A, described his difficult background, and complained that Houtarou Oreki had scammed him out of nearly three million points.

Kakeru Ryuuen tried to make Class B pay Class C for supplies and ongoing living expenses, but Honami Ichinose recognized the risks and sought an alternative. After learning Class D had allied with Class A, Ichinose agreed to a temporary alliance with Class C to keep Class B in the competition.

• Kakeru Ryuuen explained that he had ended his agreement with Houtarou Oreki to protect Class C’s points, then offered Class B supplies in exchange for monthly payments after the exam.
• Honami Ichinose rejected Ryuuen’s proposal as a risky deal and sent Shibata to check whether Class D would sell supplies to Class B.
• Ryuuen threatened to sell supplies to Class A, but Ichinose argued that he would not help Oreki’s class after cutting ties with him.
• Shibata returned and reported that Class D had allied with Class A and would sell them supplies.
• Ryuuen said Class A had confirmed 270 base points, and Ichinose agreed that Class B had to form a temporary alliance with Class C.

After the students landed on the deserted island, Oreki and Katsuragi’s group hurried to claim bases while Kōenji raced ahead to secure Class D’s locations. Kōenji told Sudou that Oreki had advised him and argued that Class D could never truly rise, so he intended to gather twenty million points himself.

• Ryuuen proposed that Class B exchange supplies with Class C on the island, but Ryuji Kanzaki insisted they assess the bases first, and Ryuuen left sneering.
• The students disembarked and received GPS wristbands; Oreki realized they could expose him if he used Teleportation to leave the island.
• Oreki, Katsuragi, Kamuro, Hashimoto, Totsuka Yahiko, and another member of the Katsuragi Faction set out to claim five bases whose locations Class D had shared with Class A.
• Kōenji took a wristband and Leader Card, then sprinted into the forest to occupy bases while Hirata sent Ayanokouji and Sudou after him.
• Kōenji told Sudou that Oreki had suggested his plan and that he intended to gather twenty million points, since he believed Class D had no future and the school would prevent it from rising.

Ayanokouji reflected on his desire to challenge Kōenji and Oreki, while Class A used Kōenji’s information to claim bases and Oreki considered why Kōenji had helped them. The chapter ended with Ryuuen’s class arriving on the island and setting out to find a base before making any deals.

• Ayanokouji considered facing Kōenji and Oreki, seeing defeat as a way to disprove his father’s faith in him, though he was unsure he could accept losing.
• Kōenji assured Ayanokouji and Sudou that he could protect the reward points, then disappeared ahead of them.
• Oreki, Kamuro, and Hashimoto surveyed the island from a White Tower after Class A claimed five bases using Kōenji’s information.
• Oreki reasoned that Kōenji had likely explored the island already and was pursuing the exam’s 200-point rating for its potential rewards.
• Kamuro’s notes confirmed that leaders could not be changed freely, though a legitimate reason could allow a change.
• Ryuuen’s class arrived, surrendered their phones, put on monitoring wristbands, and began searching for a base before trading their starting points.

Ryuuen’s Class C found that Class D had already occupied nearby bases, costing them Points and forcing Ryuuen to reconsider how to cooperate with Ichinose’s Class B. As the students struggled with hunger, thirst, and the lack of proper facilities, Ryuuen decided to exchange some Points for supplies while the teachers watched from the beach.

• Ryuuen led Class C toward a cornfield, but Hiyori noticed that the nearby base had already been occupied by Class D.
• Ishizaki returned from the beach and told Ryuuen that Class C had lost 50 basic Points.
• Class C discovered that Class D had occupied another base and avoided its vegetable fields to prevent further deductions.
• Class C students complained that they were thirsty and needed a toilet, but they rejected the school’s portable toilet.
• Ryuuen decided to spend some basic Points on supplies, while the teachers gathered on the beach and prepared to rotate their duties.

The four Homeroom Teachers monitored their classes’ GPS locations and discussed their early progress on the island exam. Hoshinomiya Chie believed Class B had an advantage through its cooperation with Class C, but wondered why all forty students were moving together.

• Hoshinomiya Chie, Chabashira, Suma Bando, and Majima opened the GPS software to track their students on the island.
• Hoshinomiya Chie saw that Majima’s Class A had secured five territories, while Ichinose’s Class B had already passed several.
• Hoshinomiya Chie recalled that Class B had arranged for Class C to provide supplies in exchange for points, helping Class B preserve its base Points.
• Hoshinomiya Chie saw that nearly all of Suma Bando’s students were staying at one territory to camp, while Class B continued moving.
• Hoshinomiya Chie wondered why all forty Class B students, including Ichinose, were traveling together when only some needed to search for territories.

Class C and Class B struggled during the deserted island exam as Class D’s movements disrupted their plans. Class B returned exhausted to the beach, and Kanzaki asked to report what had happened.

• Hoshinomiya Chie noticed that most of Class D had stayed at one base while one fast-moving student raced ahead and crossed paths with Class B.
• Daichi Ishizaki asked Suma Bando about point deductions after Class C reached a base occupied by Class D, and Class C lost 50 points.
• Kakeru Ryuuen brought Class C back to the beach, exchanged points for supplies, and warned that Class B would soon face trouble.
• Hoshinomiya Chie watched Class B return with all its supplies after carrying them across the island, exhausted and distressed.
• Kanzaki told Hoshinomiya Chie that Class B wanted to report what had happened.

Class B learned that Class D had occupied nearly every base and discovered that their fear of losing Points had driven them to walk for hours without resting. After Teacher Majima clarified the rules, Class B exchanged Points for supplies through Ryuuen, who charged them heavily.

• Class B students reached the beach exhausted and sunburned after repeatedly finding bases occupied by Class D.
• Ryuuen mocked Ichinose and Class B, then offered to sell them parasols at an inflated price.
• Ichinose asked Teacher Majima to explain the rules, while Hoshinomiya Chie and Suma Bando complained about Class D occupying the bases.
• Teacher Majima announced that students could not damage another base's resources or stay at it for more than an hour, and Teacher Chabashira maintained that Class D had not cheated.
• Class B accepted Ryuuen's help to exchange Points for supplies, and Ryuuen demanded two thousand Points each time someone used the toilet.

Class B and Class C regrouped on the beach and planned how to secure bases before nightfall, while Ryuuen arranged to identify Class D’s leader. Class B chose a vegetable garden as a base, and Ryuuen’s group waited near a Class D base as its occupation period neared its end.

• The teachers discussed Class D’s lead in occupied bases, and Chabashira insisted her students had followed the rules.
• Ichinose and Kanzaki planned for Class B to wait out a base’s occupation period and claim it for the night.
• Ryuuen ordered students to watch Class D’s and Class A’s bases in hopes of discovering their leaders.
• Class B scouts chose a vegetable garden with a well as a suitable base and estimated that supplies would cost only 50 to 60 more Basic Points.
• Ryuuen, Daichi Ishizaki, and Albert hid near a seaside base as its eight-hour occupation period approached six o’clock.

Ryuuen struggled to determine whether Kōenji was Class D’s leader or had deliberately misused a Leader Card to block access to a base. That evening, Class C failed to appear for roll call, and Katsuragi wondered whether Ryuuen was plotting something.

• Kōenji scanned his Leader Card at a base, occupied it, and left without revealing whether he was Class D’s leader.
• Ryuuen considered that Houtarou Oreki might have told Kōenji to misuse the card and planned to send a spy to identify the leaders of Classes A, B, and D.
• At the evening beach roll call, all students from Classes A, B, and D arrived, but no Class C students appeared.
• Kōenji spent Class D’s final five base points on grooming supplies, and Sudou held a mirror while Kōenji fixed his hair.
• Katsuragi noticed Class C’s absence and suspected Ryuuen might be plotting, while Class A had already secured five bases and Class B appeared exhausted.

As Class A questioned Class C’s absence from roll call, Oreki deduced that Ryuuen’s class had forfeited after arranging a deal with Class B. Oreki said Class A could still pull ahead, but wondered whether Ryuuen had truly abandoned the exam.

• Hashimoto suggested that Ryuuen might have joined forces with Class B, while Katsuragi and the others looked to Oreki for an explanation.
• Oreki considered how Class A could maximize its points but refused to take on the burden of sweeping the island alone.
• Oreki concluded that Class C had forfeited rather than missed roll call.
• Suma Bando revealed that Class C had traded base points to Class B for supplies, then forfeited because the occupied bases left them little to gain.
• Katsuragi worried that Class C’s deal with Class B threatened Class A’s lead, but Oreki said Class A could still finish ahead.
• Oreki questioned whether Ryuuen had truly given up, recalling that Ryuuen had previously worked to protect his class’s evaluation points.

Ryuuen assessed the Deserted Island exam rules and resolved to pursue more gains, while Class D decided who would remain on the island after exhausting its base Points. Sixteen students stayed behind, leaving the class split between the island and the cruise ship.

• Oreki reasoned that Ryuuen would act to prevent Class D from gaining a large bonus through its occupied bases.
• Class D discussed whether to withdraw after trading supplies to Class A and using all 300 base Points; Hirata asked half the class to stay with Kōenji.
• No one initially volunteered, and Kōenji remained silent while watching himself in a mirror.
• Horikita Suzune, Kikyou Kushida, and Meiyu Wang volunteered to stay, followed by Airi Sakura and Yamauchi.
• Ayanokouji and Sudou also chose to stay, bringing the number of Class D students remaining on the island to sixteen.

Katsuragi and Oreki investigated Class C after its students appeared to withdraw from the island exam, but Oreki suspected Ryuuen had stayed behind as Class C’s leader. They planned to confirm whether Class C could still be chosen in the leader-guessing stage on the seventh day.

• Katsuragi worried that Ryuuen’s apparent withdrawal was a trick, so Oreki agreed to inspect Class C’s base with him.
• Oreki noticed Horikita and Kikyou Kushida had stayed behind, and Kushida seemed angry that she had been excluded from Class D’s Points plan.
• Honami Ichinose and three Class B students joined Oreki and Katsuragi on their way to check Class C’s base.
• The group found Class C’s occupied base littered with food, bottles, and unused supplies, leading Ichinose to conclude that Class C had withdrawn.
• Oreki pointed out that no one had confirmed Ryuuen himself had left, and he and Katsuragi realized Ryuuen might still be on the island as Class C’s leader.
• Oreki said they could confirm their suspicion on the seventh day by checking whether Class C remained eligible in the leader-guessing stage.

Oreki warned Class A that Ryuuen could expose their leader and urged the rival factions to protect their information instead of sabotaging one another. After Kamuro brought the battered Rei Ibuki to camp, Oreki decided to take her to Ichinose at Class B Camp.

• Oreki explained how Ryuuen could identify Class A’s leader and help other classes cost them base and reward Points.
• Oreki warned Katsuragi and the others to guard against outsiders, easing tensions between the Katsuragi and Sakayanagi factions.
• Oreki returned to camp and found that Kamuro had brought Rei Ibuki, a battered Class C student, back from the island.
• Hashimoto reported that Ryuuen had beaten Ibuki again after she resisted his plan to pocket Class C’s payment from Class B.
• Oreki told Kamuro to take sugarcane and corn to Ichinose at Class B Camp and send Ibuki to her.

Oreki brought the injured Ibuki from Class A to Class B, presenting her as a victim of Ryuuen’s violence and asking Ichinose’s class for help. Class B’s response was sympathetic, but Oreki’s true intentions remained unclear.

• Oreki recognized Ibuki as the Class C spy and brought her, Kamuro, and Kito to Class B’s camp.
• Oreki offered Class B sugarcane and corn as humanitarian support and said he had a request.
• Ichinose recognized Ibuki, and Oreki explained that Ryuuen had taken Class B’s gains and that Ibuki feared returning to him.
• Ibuki followed the story Ryuuen had given her, saying she hated him and pointing out her bruised arm.
• Kanzaki agreed that Ibuki should not have to return to Ryuuen, while Oreki said Kamuro had found her.

Oreki arranged for Ichinose’s Class B to shelter Ibuki and suggested they report Ryuuen’s violence after the exam. He then spoke with Ichinose away from camp, where she revealed how exhausted the day’s search had left her.

• Oreki told Ichinose that Ibuki could testify against Ryuuen and that Class C might lose fifty class evaluation points if they reported his violence to the Student Council.
• Ichinose agreed to take Ibuki in, and Class B students eagerly tended to Ibuki’s injuries while considering how to document them as evidence.
• Oreki and Ichinose walked away from the camp to talk, and Oreki noticed that his night vision had changed after being altered.
• When Ichinose showed how tired and sore her feet were, Oreki suggested they stop walking and return to camp.

Oreki pieced together Ryuuen’s plan to leave a Class C spy with each rival class and warned Ichinose that Kōenji planned to claim most of the island’s bases. On the walk back, Oreki explained to Kamuro why he had brought Ibuki to Class B, leaving her to investigate what Ibuki had buried.

• Ichinose described Class D’s advance occupation of the bases, and Oreki inferred that Kōenji had scouted the island by swimming there the previous night.
• Ichinose revealed that Ryuuen had abandoned Kaneda, Ibuki, and Daichi Ishizaki after they opposed him, and Oreki deduced that Ryuuen had planted one of them in each rival class.
• Oreki warned Ichinose that Kōenji intended to earn six hundred class evaluation Points by occupying thirty-four bases, so Class B would likely lose the base it planned to claim.
• Oreki walked back with Kamuro and explained that Class B had found a Class C student, meaning Class D probably had one too and Ibuki might be a spy.
• Kamuro told Oreki that Ibuki’s dirt-covered hands looked as if she had been burying something, and Oreki told Kamuro to investigate.

Oreki and Kamuro found a walkie-talkie and camera buried near where Ibuki had been discovered, confirming that she was a spy. After the morning roll call, Oreki reviewed the classes’ plans and set out to explore the island for special rewards.

• Oreki had Kamuro dig near the spot where Ibuki had been found, and they uncovered a walkie-talkie and camera.
• Kamuro realized her actions could have cost Class A up to 270 class evaluation Points, so she anxiously began serving Oreki at camp.
• At morning roll call, Majima confirmed that all forty Class A students were present, and Katsuragi outlined the class’s plans for bases and supplies.
• Oreki noticed that Class B had lost its camp base to Kōenji and that Ishizaki had joined Class D as a spy.
• Oreki headed toward the White Tower before continuing his search for special rewards elsewhere on the island.

Oreki found the hidden Caretaker's Cabin beneath the Central Tower and discovered the 41st Base, while Kushida arrived and the teachers confirmed that students from Classes A and D had found it. The teachers revealed that the cabin was an Easter egg offering fifty reward points, as Ryuuen remained hidden on the island to compete in the leader-guessing segment.

• Oreki searched near the Central Tower, found a concealed ladder, and climbed down to the Caretaker's Cabin.
• Oreki found the cabin's Card Reader and confirmed that the undiscovered location was the 41st Base.
• Kushida reached the cabin, and Oreki invited her to climb down with him.
• Hoshinomiya told the teachers that students from Classes A and D had found the 41st Base.
• Suma Bando explained that Ryuuen, Ibuki, Daichi Ishizaki, and Kaneda had stayed on the island, with Ryuuen hiding to enter the leader-guessing segment.
• Hoshinomiya explained that the cabin was an Easter egg proposed by the Chairman and would award fifty points to students who found it and used its Card Reader.

Hoshinomiya Chie explained to Suma Bando that Ryuuen had planted spies in other classes, then showed him evidence that Ryuuen had assaulted Ibuki and Kaneda. She expected the Student Council to punish Ryuuen and Class C, while a conversation with Chabashira ended with Chie noting that Classes A and D were acting strangely.

• Suma Bando learned that Ryuuen's three remaining students had been taken in by Classes B and D, leaving Class B with two Class C spies and no spy in Class A.
• Hoshinomiya Chie showed Suma Bando a photo of injured Ibuki and Kaneda and said her students planned to report Ryuuen for assault.
• Suma Bando realized Ryuuen could face a 100-point class deduction and a suspension, which might cancel out the points he gained from learning other classes' leaders.
• Hoshinomiya Chie returned to the supply exchange point, where Chabashira cautioned her against casually calling students spies.
• Hoshinomiya Chie looked at Teacher Majima's computer and remarked that Classes A and D were both acting strangely.

Oreki brought Kushida to the hidden 41st Base and urged her to release the stress she had accumulated while mediating conflicts in Class D. He then returned to the cabin to choose books, leaving their arrangement and the island exam ongoing.

• Oreki noticed Kushida following him after roll call and led her to the hidden 41st Base.
• Oreki explained that Kushida could not leave the island because Class D needed her to mediate conflicts, and he offered her a private place to vent.
• Kushida admitted that she wanted to kick the wooden post and release her pent-up emotions.
• Oreki returned to the cabin and picked up David Copperfield and Humiliated and Insulted from its bookshelf.
