• The President reveals she has pieced together fragments of Mo Bai’s past from Christopher’s script, despite the parts about him having disappeared.
• She offers to help make Rover “more perfect,” appealing to Mo Bai’s desire to protect and support his friend.

• Napomo invites Mo Hei to join them, and Siglica eagerly agrees. Mo Hei accepts because she wants to keep an eye on Dania—and hopes she might belong with the group.

• Mo Hei shares secretly taken photos of Napomo, whose earlier “careless” mistake still strikes Mo Bai as suspicious. However, there is not yet enough evidence to act.
• Mo Bai recalls that Napomo received treatment at Lu’s Infirmary and believes this could provide a lead. He says he has someone in mind to consult the following day.

• Students celebrate with stalls, gadgets, games, and other activities. The Academy’s “Dark Side” offers a riskier way to relieve stress: students confront themselves, though the experience can cause lasting harm, so an emergency escape system is available.
• Mo Hei, newly free from her surveillance assignment, wanders the festival looking for her friends. Dania tells her Siglica is investigating the Dark Side and suggests Mo Hei go there too. Mo Hei accepts, seeing it as a chance to face herself.
• Dania watches Mo Hei leave, troubled because she has directed her there as part of her organization’s plan. She also feels she is failing Siglica, and hopes the Rover will intervene.

• The Sonoro reshapes itself around visitors’ emotions. Mo Hei recalls seeing dark energy around Siglica, which he understands as bottled-up pressure. Yet he sees no reflection of his own darkness and wonders whether his lost memories are responsible.
• Mo Hei rushes onward, unaware that his poor control of Cursed Energy may have caused an abnormal presence to appear nearby.
• The President of the Remnant Star Society realizes her plans have been disrupted: her hidden Artificer has been destroyed, and Mo Bai has taken the White Rabbit she had prepared.

• Rover, Siglica, and Mo Hei go to Principal Losera’s office, where Mo Bai has been helping Losera manage pressure from the Academy’s leaders and outside organizations.
• Mo Bai explains that unstable Cursed Energy leaking from Mo Hei resonated with the Dark Side’s negative emotions, creating Cursed Spirits. He suspects the sheer number of monsters cannot be explained by that alone.
• Rover and Mo Bai independently suspect the Remnant Star Society is responsible, though they have no proof. Mo Hei is troubled by the possibility that her own power helped cause the disaster.

• Rover stays focused on the urgent task, guides the group to Losera, and quickly identifies the Remnant Star Society as a likely culprit.
• Mo Bai takes charge of explaining the Cursed Spirits and recognizes that Mo Hei’s energy alone should not have produced so many. His awareness of her experience through Nue’s memories also underscores their close connection.

Significant themes

• Responsibility and guilt: Mo Hei may have contributed to the crisis, even if unintentionally.
• Independence versus reliance: Her promise not to depend too heavily on Mo Bai clashes with her instinct to seek him out in danger.

Chapter Summary

Key plot points and events

• Losera receives an update that someone has tampered with the Academy’s Dark Side and controls who can enter or leave.
• Students trapped in Sonoro are temporarily protected: Losera has an informant there, and Chisa is also present.
• Since forcing entry could endanger the students, Losera identifies Mo Hei and Siglica as the only ones currently able to enter under the enemy’s rules. She plans to keep seeking another way in.
• Mo Hei volunteers to go, moved by empathy for the frightened students and by her sense of responsibility for how the crisis began. Siglica agrees to join her.
• Losera sets their entry for that afternoon and encourages them to rest. Instead, Mo Hei goes to the garden, while Siglica seeks comfort from her friend Dania.
• Mo Bai joins Mo Hei and apologizes for having avoided her earlier. After she explains her doubts about her abilities, missing memories, and unusual connection to the Dark Side, Mo Hei asks him what they were to each other in the past.

Character developments and interactions

• Mo Hei chooses to face danger despite doubting her strength. Her compassion for the students echoes her own disoriented experience when she first arrived at the Academy. She also begins confronting her deeper uncertainty about her identity and past.
• Siglica shares Mo Hei’s anxiety but still volunteers to enter the Dark Side. She turns to Dania for support.
• Mo Bai recognizes that helping Mo Hei become independent does not mean leaving her alone. He apologizes, listens to her concerns, and becomes the person she trusts enough to ask about their shared past.
• Losera balances reassurance with caution: she protects the students as best she can while seeking an alternative to a risky direct entry. She quietly asks Mo Bai to support Mo Hei.
• Rover questions the plan and is asked to stay behind with Losera.

Significant themes

• Responsibility and compassion: Mo Hei accepts danger not from grand ambition but from empathy and a wish to prevent others from suffering as she did.
• Independence and support: Mo Bai’s realization—and his conversation with Mo Hei—suggest that self-reliance need not mean facing hardship alone.
• Identity and memory: Mo Hei’s unexplained abilities, connection to the Dark Side, and forgotten past fuel her central question about who she is and what she meant to Mo Bai.
• Fear beneath resolve: Both girls agree to act, but privately struggle with the weight of expectations and uncertainty.

Key plot points and events

• Mo Hei realizes that she and Mo Bai share a past: their resemblance, matching Cursed Energy, and Nue’s familiarity with her give it away.
• Mo Bai stops hiding the truth and demonstrates his Ten Shadows Technique, including summoning Shikigami, manipulating shadows, and creating [Light] through Cursed Technique Reversal.
• Mo Hei cannot recall their history, but asks Mo Bai to tell her everything about their time together before they go to Sonoro.
• At the Academy cafeteria, Siglica seeks out Dania but struggles to explain what is troubling her. She eventually reveals that she and Mo Hei will enter the Academy’s Dark Side after an incident there.
• Siglica admits she fears the students’ expectations more than the enemies. Dania tells her she can run away rather than shoulder a dangerous mission for others’ sake.

Character developments

• Mo Hei becomes more at ease about her lost memories. Being with Mo Bai matters more to her than recovering them immediately, and she trusts him to recount their shared past.
• Mo Bai chooses honesty, recognizing that continued secrecy would only burden Mo Hei. His recollections suggest she once relied heavily on him.
• Siglica reveals her vulnerability beneath her brave public image: she feels overwhelmed by the hopes others place in her.
• Dania shows that her loyalty is to Siglica as a friend, not simply to the organization’s mission.

Significant themes

• Memory and identity: Mo Hei’s forgotten past shapes her curiosity, but present trust offers comfort even without answers.
• Expectations and responsibility: Siglica’s fear comes less from the mission’s enemies than from the pressure to fulfill others’ hopes.
• Friendship and compassion: Both Mo Bai and Dania respond to their friends’ needs with honesty and reassurance rather than pressure.

Character interactions

• Dania gently draws Siglica into speaking, recognizes what truly frightens her, and gives her permission to refuse the mission.

Key plot points

• Losera prepares Mo Hei and Siglica to enter the Academy’s Dark Side, where they will likely be separated. She tells them that White Rabbit will guide them and that their priority is to help the trapped students escape—or, if necessary, protect them until the Academy’s backup plan can be used.
• White Rabbit, once captured by Mo Bai, has agreed to work for Losera. It can travel freely through the Dark Side and now carries a Paper Crane placed inside it by Feixue.
• Mo Hei and Siglica enter without hesitation.
• In the chaotic Dark Side version of Sonoro, Siglica runs from Cursed Spirits that repeat the pleas and demands she finds so burdensome. She fights back decisively, cutting down a spirit that blocks her path, and sets out to find the other students.
• Mo Hei encounters a very different scene: the Cursed Spirits near him lie still and show no hostility. He suspects his connection to the Cursed Energy behind them may explain their behavior, but realizes the mastermind may react by making his situation more difficult.

Character development

• Siglica recognizes that her pressure is not simply imposed by others: she has turned classmates’ compliments and kindness into standards she feels obliged to meet. Though gentle in appearance, she is stubborn and capable of decisive action when confronted by the fears she has buried.
• Mo Hei is cautious and observant. He notices Siglica’s distress and is surprised she volunteers, while also anticipating that the enemy may adjust its tactics once it sees his unusual immunity.
• Losera acts as a practical leader, giving the pair clear objectives and a fallback plan while allowing them to commit freely.
• White Rabbit has shifted allegiance out of self-preservation, believing its former master would discard it.

Significant themes

• Confronting buried emotions: The Cursed Spirits embody Siglica’s accumulated negative feelings, forcing her to face them directly.
• Self-imposed pressure: Siglica’s distress comes partly from turning kindness and praise into expectations she must live up to.
• Courage and agency: Both students knowingly accept the danger, while Siglica’s response shows she can resist rather than flee indefinitely.
• Uncertainty and adaptation: The Dark Side behaves differently for each student, and Mo Hei’s apparent advantage may provoke the mastermind to change the challenge.

Character interactions

• Losera briefs Mo Hei and Siglica together, and her reassurance emphasizes that their task is to help the other students rather than solve everything alone.
• Siglica recalls Dania’s advice and Yaya’s encouragement, but chooses to trust the genuine kindness of her classmates while acknowledging her own role in creating her pressure.
• Mo Hei’s concern about Siglica contrasts with her firm decision to participate.
