Kumiko’s killing of her brother

Kumiko’s killing of her brother is presented through her final message to Toru and the aftermath he recounts to May Kasahara. Kumiko leaves for the hospital intending to kill her brother and accept punishment; later, Toru explains that she has refused release from jail and plans to plead guilty. The episode turns a private decision into a deliberate acceptance of its legal consequences, while leaving Kumiko apart from Toru as she waits for the case to be settled.

The Decision and Its Meaning

In her message, Kumiko says that time has run out and that a taxi is waiting to take her to the hospital. She states that she will kill her brother and take her punishment. The decision is not presented as an eruption of hatred: she says that she no longer hates him and feels calm about what she is going to do. She describes the act as being for his sake as well as her own, and as a way to give meaning to her life.

Her explanation joins an act against another person to a claim about responsibility and purpose. The message does not disclose further circumstances of the killing or explain precisely what she means by acting for her brother’s sake. Its emphasis instead falls on her stated resolve and on the punishment she expects to face.

The Message to Toru

Kumiko’s note is sent from the computer in her brother’s office, after she has received its access password by special delivery. With the taxi waiting outside, she has little time to write. Her closing instructions are practical and intimate: she asks Toru to take good care of the cat, is glad that he has returned, and approves of the name Mackerel. She remembers the cat as a symbol of something good that grew between her and Toru and says they should not have lost him when they did.

The cat gives the message a second emotional register. Alongside the announcement of a killing and its consequences, Kumiko recalls a shared bond that survived the separation. Her goodbye ends the communication without resolving the distance between them or offering a promise of reunion.

Imprisonment and the Pending Trial

Later, Toru tells May Kasahara that Kumiko refused to be released from jail. She believes she would be mobbed outside and prefers the quiet of confinement; she is not seeing Toru or anyone else until the matter is settled. Her refusal makes imprisonment, at least for the time being, a condition she chooses rather than an outcome she asks Toru to undo.

Toru says that Kumiko is pleading guilty and will accept the verdict, whatever it is. He expects a short trial, sometime in the spring, and believes that a suspended or otherwise light sentence is possible. Those expectations are Toru’s, not a final legal outcome: the account leaves the trial and its verdict pending.

Consequences and Narrative Significance

The episode places Kumiko’s decision beside two forms of separation: her isolation in jail and her refusal to see Toru. Yet the message preserves a connection through the cat and through her memory of what was good in their marriage. Her stated acceptance of punishment gives the action a consequential ending without supplying a complete account of its circumstances or legal resolution.

Toru’s later conversation with May frames the aftermath as an unresolved wait. Kumiko will not see him, the trial has not yet taken place, and he expects to remain at home waiting for her. The contrast between her decisive departure for the hospital and his continuing uncertainty leaves their shared future open.
