Suitcase

The Suitcase links Nanao’s assignment to Tangerine’s search for Lemon, turning a portable object into the focus of competing priorities. Tangerine wants to secure it before it disappears again; Nanao eventually takes it by the handle and considers leaving the Shinkansen with it. Its custody matters not only because Nanao was hired to steal it, but because carrying it is the condition he believes will let him finish the job and get away.

Custody and Identification

When a conductor appears, Nanao points toward Tangerine and tells him that the Suitcase he had given the conductor earlier belongs to Tangerine. The conductor says he had already announced that it was unclaimed and that it remains in the crew room, then offers to take them to collect it. The exchange gives the case a clear, practical status: it is a missing item that can be retrieved from railway staff, as well as the object Nanao has been tasked with stealing.

Tangerine does not immediately follow without reservation. He has not searched the whole train for Lemon, but the possibility of losing the Suitcase again weighs on him. He decides it is better to secure it while he has the chance. The case therefore competes with the search for his partner: Tangerine must choose which urgent concern to pursue first, and the conductor’s offer gives him a route back to the property.

Nanao’s Mission and Choice

Later, Nanao takes the Suitcase by its handle while preparing to leave. He has just expressed a wish to be done and to get off the train; the handle makes the assignment concrete in his grasp. The case is not incidental baggage to him. Nanao understands his job as stealing it and getting off the Shinkansen, so leaving with it would mean carrying the task through to its essential conclusion.

His confidence in that plan is qualified. With Tangerine and Lemon gone, Nanao cannot predict what Minegishi will do, though he thinks Minegishi’s anger would probably have fallen on the two men rather than on him. If Nanao leaves at Ichinoseki Station with the Suitcase, he expects to avoid trouble. He admits to himself that the result might not earn a perfect score, but imagines it could still be a low A. That private grading scale makes the case a measure of a job assessed as performance, even while the danger surrounding the assignment makes success uncertain.

A Way Out, Not a Clean Escape

Nanao’s handling of the Suitcase sits beside his effort to discard other connections to the danger around him. He throws away Tangerine’s phone, says he wants to be finished, and takes the case. The actions distinguish what he is willing to abandon from what his assignment still requires him to carry: he tries to shed the phone, but the Suitcase remains necessary to the exit he is imagining.

The announcement for Ichinoseki Station arrives at what seems to Nanao like perfect timing. Yet the schoolkid asks him to stay until Morioka because he is scared, interrupting the simple departure Nanao had pictured. Nanao’s plan depends on the Suitcase and on being able to get off; the request forces him to confront a human obligation at the same moment that escape appears available. The case can be carried out of the train, but it cannot by itself make the consequences of leaving disappear.

Narrative Function

The Suitcase repeatedly reorganizes the characters’ immediate choices. For Tangerine, it is something to secure while Lemon remains missing. For Nanao, it is both the object of a paid task and the means by which he hopes to conclude that task. Its movement through railway custody and back into Nanao’s hands gives these competing aims a visible center, while the contrast between the case’s straightforward retrieval and Nanao’s uncertain expectations keeps the promised escape provisional.
