Yasunobu Endo and Yumi’s romantic relationship

Yasunobu Endo and Yumi’s relationship was an intimate connection formed within the hostess-club world: Endo was a regular customer who courted Yumi with meals and gifts, and their association became sexual without, in Yumi’s account, becoming love. Its significance lies in that distinction. She missed him after his disappearance, yet described their bond as a mixture of attraction, curiosity, companionship, and the transactions of the club rather than a declared romance.

A relationship formed at the club

Yumi worked as a hostess, and Endo was among the club’s regular customers. When investigators traced Endo’s last hours, they learned that he had called her at nine in the evening after taking part in illegal gambling. The call was brief: he said he would be a little late. It offered a small, ordinary detail about his evening, but no explanation of where he was going or whom he intended to meet.

After tracing the call, Sekiguchi located Yumi. The following evening, the narrator and Yoshihara visited the club where she worked. Yumi was initially alarmed when Yoshihara explained their purpose, but she agreed to speak with them on the terms of her workplace: they were customers, and she expected them to behave like good customers. She specifically asked them to buy champagne. The interview therefore took place inside the social and commercial setting that had brought Endo and Yumi together, with information exchanged over a bottle they ordered.

Attraction, gifts, and sex

Yumi recalled Endo as older than she was and as a gentleman who had wined and dined her and bought her lavish gifts. She also remembered his animal magnetism. The account joins material generosity and personal attraction without reducing one to the other: Endo’s courtship took place through the spending and attentions of a regular patron, while Yumi described a physical pull that made her curious enough to sleep with him.

That curiosity became sexual intimacy, and Yumi said she discovered that Endo was good in bed. Her recollection is frank but not sentimental. She did not present the sexual relationship as proof of love or as a promise of commitment; instead, it appears as one part of an attachment that grew through repeated visits, gifts, and time together. The evidence shows what she chose to tell investigators, not a fuller account from Endo’s perspective.

The body remembered, the future unknown

Yumi also recalled a physical contradiction in Endo: his tattoos made his skin feel cold. She compared sleeping with him to sleeping with a snake, pleasant in summer but not in winter. The image gives her memory an uncomfortable edge. It sits beside her description of his generosity and sexual appeal, complicating the portrait without displacing her attraction to him.

After Endo vanished, Yumi said she missed him, though she had never been in love with him. The distinction keeps grief and romance from being treated as interchangeable: his absence mattered to her, but she did not recast their relationship as a love story. Her last known contact was the brief call in which he said he would be late. She did not know whom he was going to meet, and said she rarely discussed his work with him. The call thus marks both the relationship’s ordinary intimacy and its limit: Yumi knew his habits as a customer and lover, but could not account for the final movements that led into his disappearance.

The relationship’s place in the investigation

Yumi’s account gave investigators a personal view of Endo that the trace of a phone call alone could not provide. It established the nature of their connection, the affection and attraction she remembered, and the fact that his last known communication had been with her. Yet it did not solve the central uncertainty surrounding his final evening. The relationship brought the investigation close to Endo’s private life while leaving its most consequential question unanswered: where he went after telling Yumi he would be late.
