Chapter Summaries

Oreki and Horikita waited in Oreki’s room while Kōenji volunteered to swim to the Deserted Island and scout it. Oreki asked Kushida for conversation topics, but Kushida froze after learning Horikita was with him, and the chapter left her with Sakura in their dorm room.

• Kōenji offered to swim to the Deserted Island at night and report what he found, while Oreki decided to let him go rather than teleport there himself.
• Oreki and Horikita waited together in his room, but neither could think of anything to do or talk about.
• Oreki messaged Kikyou Kushida for help easing the awkward atmosphere, and Kushida quickly realized Horikita was with him.
• Kikyou froze over Oreki’s message as Sakura came out of the washroom and told her it was her turn to wash up.
• Kikyou reflected on how she had grown closer to Sakura while Horikita was away, and wondered why Horikita had not returned to their room.

Oreki tried to find a topic to discuss with Horikita Suzune, and their conversation about her future revealed that she had not formed plans of her own. Kōenji then called from the deserted island and reported finding about forty Card Readers, leaving the students with a possible lead on the island’s bases.

• Kushida sent Oreki two documents with conversation topics, along with a cynical message about people’s motives.
• Oreki asked Horikita Suzune about her future, and she said she had no plans beyond collecting twenty million points.
• Oreki suggested Horikita might become a lawyer, and she began considering it as a suitable future without offering a separate ambition of her own.
• Kōenji video-called Oreki from the deserted island and reported that it was artificial and divided into areas with Card Readers.
• Kōenji said he had dismantled a Card Reader, found its battery had recently been replaced, and estimated that around forty readers could be claimed.

Oreki picked up Kōenji after his swim and watched the cruise ship return toward the island as the students prepared for the exam. At breakfast, Class A’s contempt for Class D caused a confrontation, while Kamuro recorded the meal for Sakayanagi Arisu.

• Kōenji shared information with Oreki and Horikita before swimming back from the Artificial Island, and Oreki went to pick him up.
• Oreki received late-night messages from Kikyou Kushida, who complained that Horikita seemed healthy and disliked her even more.
• The cruise ship changed course toward the Deserted Island, and Oreki ate breakfast with Class A at Esther.
• Yamauchi, Ike Kanji, Sudou, and Kiyotaka Ayanokouji entered the restaurant, where Totsuka Yahiko insulted them and Katsuragi told them to behave properly.
• The Class D boys left, and Kamuro told Oreki she was recording meals for Sakayanagi Arisu.

Oreki told Katsuragi that Kōenji had already explored the Deserted Island, then gathered Horikita and Kikyou to discuss using Ryuuen's points for a money-making plan. The group approached Ryuuen on the deck, while Kikyou mistook Oreki and Horikita's handshake for a sign that they were dating.

• Kamuro insisted she could catch up academically and stop needing Sakayanagi, while Oreki warned that Sakayanagi had her weakness.
• Katsuragi told Oreki the cruise ship was nearing the Deserted Island and suggested observing it, but Oreki revealed that Kōenji had already swum there.
• After eating, Oreki invited Horikita and Kikyou, planning to raise Kikyou's favorability and discuss Ryuuen's money.
• Oreki shook Horikita's hand to use his Restoration Ability, and Kikyou misread their interaction as evidence that they were dating.
• Oreki, Horikita, and Kikyou approached Ryuuen, who was leaning against the deck railing beside Albert Yamada.

Houtarou Oreki sold Kakeru Ryuuen information about the deserted island for 100,000 Points, prompting Ryuuen to seek camera equipment before the special exam began. After the announcement, Oreki transferred the Points to Horikita and Kikyou Kushida, and the first-year students gathered on deck as the chapter ended with Kushida smiling at him.

• Ryuuen revealed that he had only 103,000 Points left, and Oreki sold him information that the exam would involve the deserted island.
• Ryuuen transferred 100,000 Points to Oreki and hurried off with Albert to borrow camera equipment.
• Oreki told Ryuuen that the information came too late to prepare, just as Teacher Majima announced the special exam and ordered the students to gather on deck.
• Oreki transferred the Points to Horikita and Kikyou Kushida, then prepared with them for the exam.
• The first-year students assembled by class on the deck, and Kikyou Kushida turned back and smiled at Oreki.

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.
