Halcion

Halcion is a sedative whose role in the story shifts from private means of sleep to a tool Chiaki uses to control a dangerous encounter. Its effects leave her physically and mentally impaired, and its use against Kawashima Masayuki gives her temporary power over him without resolving the uncertainty and fear between them.

Use and Circumstances

Chiaki takes Halcion after an all-night job, late on Wednesday morning, and wakes on Friday afternoon after sleeping for about fifty hours. She is still heavy and stiff despite the electric blanket being set high, and she knows that she has been gradually increasing the dosage. The long sleep leaves her with little time to prepare for an appointment at the Keio Plaza Hotel, while her employer is repeatedly trying to reach her about the appointment and the money she has not yet brought to the office. The drug’s effects thus disrupt both her ability to function and the practical demands of her work.

The source of the tablets is precarious. Chiaki knows that the shop in Shibuya where she buys them may be under investigation, and she is concerned that they are expensive. These details place her use outside an evidently secure, supervised routine. The story does not give a clinical account of Halcion; it follows Chiaki’s own experience of taking it and her decisions about using it.

Effects on Chiaki

After waking, Chiaki finds that the music playing is not the string music she remembers choosing before sleep, but the theme from Wild at Heart. The mismatch, together with her missing memory of putting on the disc, makes her wonder whether her uncertainty is only an effect of the tablets. She reconstructs the previous night from clues, including the music and the fact that she is not wearing underwear, and concludes that she probably tried to summon sexual desire before the third tablet took effect. Her account makes the drug part of a larger crisis in which she doubts both her memory and her capacity to feel.

On an earlier occasion, Chiaki took Halcion while unable to sleep beside a client. Her handbag, where she kept the tablets, was out of reach, so she remained awake until dawn rather than taking more. She feared that a recurring episode called The Nightmare might be beginning, although the watching figure she expected did not appear. The episode nevertheless left her frightened and physically tense. For Chiaki, the absence of desire is itself alarming because she associates it with the beginning of that cycle; the drug can bring sleep, but it does not remove the fear that accompanies her changing mental state.

Her knowledge of Halcion also shapes what she expects from it. She has previously put roughly three tablets into another person’s food, although that person used the drug regularly. When considering Kawashima, she assumes he is not a regular user and estimates that two tablets will affect him within half an hour and render him unconscious within an hour. She also worries that Halcion’s bitter taste might be detectable. These are Chiaki’s expectations, based on her experience, rather than a general explanation of the drug’s effects.

Use Against Kawashima

When Chiaki becomes afraid that Kawashima may leave, she decides to mix Halcion into his soup. She conceals crushed tablets in a dark glass spice bottle whose label says thyme, then adds extra curry powder to disguise the bitterness. She puts the equivalent of about two tablets into the meal. Kawashima eats the soup and two rolls without suspecting that it has been drugged; he has not eaten since buying a sandwich at Haneda Airport, and he is already tired.

Chiaki expects the dose to put him to sleep, but its effects in the scene are more disruptive than a simple transition into rest. Kawashima becomes confused and experiences an intensely frightening vision, loses his hold on the table, and calls out Yoko’s name. Chiaki initially takes his distress as evidence that the tablets have worked, then recognizes the name he is saying. Her reaction changes abruptly to rage. The drug has given her an advantage, but it has also exposed a personal connection that changes how she responds to him.

Later, while Kawashima is struggling to speak, Chiaki attributes his reduced experience of pain and his slurred words to Halcion. He invokes memories of his childhood while trying to explain how he endures pain. This moment links the drug’s immediate effects to the story’s wider concern with pain: what a person feels, what they try to suppress, and the methods they develop to survive it. The medication does not settle the confrontation or make Kawashima harmless; it is one element in a volatile encounter that continues to affect both of them.

Aftermath and Narrative Role

Chiaki believes the drug will keep Kawashima unconscious for hours after the confrontation. While he is down, she cuts herself free, finds his notebook and a concealed package containing a dangerous knife in his overnight bag, and reads the notebook. The discovery makes her question whether he is a criminal or merely someone who fantasizes about being one, but she decides that he is not the rescuer she had imagined. Halcion has created the interval in which she can inspect his belongings and reconsider who he is, yet it cannot tell her how to interpret what she finds.

When Kawashima wakes, he gradually remembers the previous night. Chiaki is preparing to pierce her other nipple, and he sees the needle in her hand; she continues with the piercing after meeting his gaze. She expects that he may leave, and her decision to choose a painful act for herself reflects her attempt to become stronger before facing that loneliness. Halcion’s role in the story therefore remains double-edged: it is a means by which Chiaki seeks sleep and briefly gains control, but it also accompanies memory gaps, frightening changes in awareness, and an encounter whose emotional consequences persist after its sedative effects have passed.
