Nanao–Tangerine hostility and temporary cooperation

Nanao–Tangerine hostility and temporary cooperation is a shifting relationship aboard the Shinkansen, shaped by a missing suitcase, Minegishi’s anger, and the death of Minegishi’s son. Nanao repeatedly tries to redirect the conflict away from a direct confrontation, while Tangerine first seeks to make him the scapegoat and later accepts a limited truce when Nanao offers information about the killer. Their brief alignment never becomes trust: Tangerine’s final response is to prevent Nanao from leaving.

Origins of the Hostility

Nanao’s first effort to manage the relationship is a phone call made from the train’s gangway. He tells Tangerine that he is not his enemy and admits that he took the bag, explaining that he acted on Minegishi’s orders. The explanation is also a tactical appeal: Nanao’s immediate aim is to stop Tangerine from coming after him. He argues that Minegishi benefits if the two men turn against each other, presenting their conflict as something their employer can exploit rather than as an inevitable personal feud.

Tangerine does not accept that account as a basis for cooperation. With Lemon present, he answers Nanao’s attempt at explanation by describing a plan to blame him for both the missing bag and Minegishi’s son’s death. The accusation makes the conflict more dangerous than a dispute over property. Tangerine says he expects Minegishi’s anger to fall chiefly on Nanao and believes that killing him could even earn the partners approval. Nanao therefore faces an opponent who is not merely trying to recover the suitcase: Tangerine is prepared to make him answer for two failures and sees violence as a way to protect himself and Lemon.

Nanao’s Attempt to Withdraw

When they speak again, Nanao changes tactics. Rather than continue disputing blame or propose a deal, he tells Tangerine that he gives up. He says he does not know the suitcase’s lock combination or what it contains, and explains that he wants to hand it over. His offer is framed as a way to end their pursuit of one another: he says he has given the bag to a conductor, asks Tangerine and Lemon to retrieve it and go to the back of the train, and says he will leave at Sendai and abandon the job.

This is not a reconciliation. Nanao presents withdrawal as preferable to remaining a target of both men, while Tangerine reminds him that abandoning the job risks angering Maria and Minegishi. The exchange leaves their practical interests partly aligned—they both have reason to fear Minegishi’s reaction—but does not establish a shared plan. Nanao wants distance and an exit; Tangerine continues to treat him as responsible for the crisis. The promised handover also does not settle the larger conflict, since the death of Minegishi’s son remains attached to the blame Nanao is trying to escape.

The Conditional Cessation of Hostilities

A more substantive pause follows after Nanao has fought the woman who killed Minegishi’s son. When he encounters Tangerine again, he keeps a gun trained on him and explains that he has found the killer: Hornet. This changes what Nanao can offer. He is no longer asking Tangerine to accept only his account of the suitcase or his proposal to quit; he is bringing information about the death that has made him a target.

Tangerine asks where Hornet is. Nanao says he cannot be sure, but believes someone else is involved. Tangerine considers this and agrees to a cessation of hostilities. The agreement is narrow and conditional in practice: it follows the disclosure of a more consequential lead, not a resolution of Nanao’s earlier responsibility for the bag or an admission that Tangerine’s accusations were wrong. Nanao answers that he did not start hostilities, while recovering his balance and putting his gun away. His reply preserves the distinction between agreeing to pause and accepting Tangerine’s framing of their relationship.

Cooperation Without Trust

The later exchange shows the limits of the truce. Nanao tells Tangerine that the suitcase is in the crew room and that the woman responsible for Minegishi’s son’s death is in the multi-purpose room beyond the green car. He says he is getting off at Ichinoseki and wants to leave both the train and the job. Tangerine points a gun at him and says he is staying. The new information has not made Tangerine willing to let Nanao choose his own departure.

Across these encounters, Nanao’s approach alternates between explanation, attempted withdrawal, and cooperation through information. Tangerine’s shifts are narrower: he first rejects Nanao’s appeal and plans to blame him, then accepts a temporary halt when the Hornet lead becomes useful, and finally compels him to remain involved. Their relationship consequently contains a real but limited change—the move from open pursuit to a negotiated pause—without a stable alliance. The suitcase and the accusation over Minegishi’s son keep pulling them toward conflict, while the search for Hornet gives them a reason, for a time, to act in the same direction.
