Minegishi's son

Minegishi's son is the young man whose death aboard the Shinkansen transforms the missing-bag problem into a crisis involving his father and the search for someone to blame. Though he has no active role in the scenes described, his body, his father’s concern, and the uncertain cause of his death shape the decisions and fears of those around him.

Identity and Circumstances

He is identified as Minegishi’s son, a young man traveling on the Shinkansen while accompanied by two men his father trusted. The account does not establish more about his personal history or character. His presence on the train becomes apparent through the discovery of his body and the later conversation about his condition.

Death on the Train

Nanao recalls seeing a young man beside Tangerine and Lemon who was not breathing or moving. Once told that Minegishi’s son is dead, he recognizes the body as the one he had seen and understands that its identity gives the death consequences beyond the immediate discovery. The account confirms the death, but does not show the moment it occurred or establish its cause.

The lack of visible wounds prompts a possible explanation. Nanao suspects that Hornet may have poisoned the young man. Tangerine describes a rumored method involving two needle pricks: the first primes the immune system, while the second can provoke a fatal allergic reaction. This account makes Hornet a plausible suspect in the conversation, but the evidence presented does not confirm that Hornet was responsible or that this method caused the death.

Blame and the Search for a Killer

Tangerine and Lemon discuss giving Minegishi the person they consider responsible for his son’s death. They identify the intended target as Glasses Guy and weigh whether to kill him or bring him to Minegishi alive. Keeping him alive, they reason, would avoid the complications of moving a body and would make the handover easier. Their discussion treats the young man’s death as a problem with immediate practical and criminal consequences, while the identity of the killer remains an assertion rather than a proven conclusion.

For Nanao, that plan makes the young man’s identity terrifyingly important. He had suspected from overheard conversation that Minegishi’s son was dead, but confirmation forces him to consider what Minegishi might do when he learns the truth. Nanao imagines a father’s grief turning to rage if he learns who was responsible. This is Nanao’s fearful anticipation, not evidence of Minegishi’s response after receiving confirmation.

His Father’s Concern and Narrative Role

Minegishi’s question about whether his son is all right reveals that he has not yet been told plainly that the young man is dead. He explains that someone called to report that his son looked wrong on the train and was not moving, with his breathing uncertain. Minegishi had initially trusted that the two men he hired were accompanying his son and that there was nothing to worry about; the caller’s warning unsettles that assurance. The account thus places a father’s concern beside the other characters’ knowledge of the death, creating a stark difference between what Minegishi fears and what has already happened.

The young man functions as the absent center of an escalating conflict. His death links the train’s passengers to Minegishi’s power, gives Tangerine and Lemon a reason to seek a person they can deliver as the killer, and leaves Nanao anticipating the danger of the father’s grief. Yet the cause of death and the responsibility assigned to Glasses Guy remain unresolved in these scenes.
