Minegishi's son's death

Minegishi's son's death changes the stakes aboard the Shinkansen: the missing suitcase is no longer the only reason Nanao may be blamed, and the dead young man is the son of the powerful Minegishi. Nanao has already seen the body beside Tangerine and Lemon, but only when Tangerine confirms the death does he understand its full implications. The account establishes the death, while leaving the precise cause unresolved: Nanao proposes that the Hornet may have used poison, but presents this as a possibility, not a proven explanation.

Recognition and Its Consequences

Nanao first learns the truth from Tangerine, who says that Minegishi's son is with them and is dead. Nanao is stunned. While spying on an earlier conversation, he thought he had heard an indication that the young man had died; now that suspicion becomes fact, and he needs a moment to absorb what it means. The realization is especially consequential because Tangerine has just connected Nanao to two liabilities: the disappearance of the suitcase and the death of Minegishi's son. Nanao is therefore not simply being told of a death; he is being made to understand that the dead young man may become part of the case against him.

The confirmation also reorganizes Nanao's memory of what he has already seen. He recalls the young man's body next to Tangerine and Lemon, and recognizes that it was not breathing or moving. The sight had made the death apparent, but Nanao had not yet understood the young man's identity. Once he learns that the victim is Minegishi's son, his thoughts turn to why the young man had to be on this train and why the surrounding events are happening to him. His response is frustration and alarm rather than a detached assessment of the body. Tangerine, by contrast, treats the news as a serious complication without showing comparable concern.

A Possible Cause, Not a Settled Explanation

The death's lack of visible wounds leads Nanao to offer a theory: the Hornet may have poisoned Minegishi's son. That possibility emerges during a conversation in which Tangerine has challenged Nanao to identify the killer. When Nanao suggests that the killer is aboard the train, Tangerine recognizes the implication and asks whether he means the Hornet. Nanao links the suspect to the son's death specifically because the body shows no apparent external injury.

The explanation remains provisional. Tangerine says that the Hornet is rumored to use needles to provoke anaphylaxis: an initial prick supposedly sensitizes the victim, while a second triggers a severe allergic reaction and death by shock. This account supplies a mechanism that could explain an apparently unwounded victim, but it is presented as professional rumor, not as a confirmed finding about this death. Nanao's suggestion therefore opens a line of suspicion without resolving who killed Minegishi's son or establishing how the young man died. The distinction matters: the body is identified as dead, while the proposed method and culprit remain uncertain.

Minegishi Seeks Confirmation

Minegishi's concern reaches the train through a call from an unnamed person who says that something about his son does not look right. Minegishi initially dismisses the possibility that the young man could be alone on the Shinkansen: he believes he has arranged for two men he trusts to accompany him. The caller's warning challenges that confidence, cautioning him not to assume that the escorts are trustworthy and reporting that the son is not moving and may not be breathing.

After receiving this information, Minegishi asks Tangerine directly whether his son is all right. The question is so direct that Tangerine does not know how to answer. The exchange brings the death into the relationship between the father and the men assigned to accompany his son: Minegishi's assurance that he had entrusted the young man to trusted escorts now stands against the caller's warning and the body Nanao has seen. The account does not identify the caller or explain how that person learned of the son's condition. It does show Minegishi moving from confidence in the arrangement to seeking an answer from Tangerine.

Narrative Significance

The death connects three strands of the train's crisis: Nanao's missing-suitcase problem, the question of who killed the young man, and Minegishi's reliance on the two men accompanying his son. For Nanao, the new information converts an earlier suspicion into a direct threat of blame. For Tangerine, the death is a problem entangled with his responsibility for the young man and with the possibility that the Hornet is aboard. For Minegishi, the warning exposes the limits of his confidence in the arrangements he made.

The narrative distributes knowledge unevenly. Nanao has seen the body before he understands whose body it is; Minegishi has received a warning but still asks Tangerine for confirmation; and the suspected poisoning method arrives as rumor rather than proof. This sequence makes recognition itself consequential without pretending that recognition supplies a complete explanation. Minegishi's son's death is certain, but the evidence here does not establish the killer, the method, or how the caller learned that something was wrong.
