Music played in a wedding hall in western Japan as Yurina Noguchi, wearing a white gown and tiara, dabbed away her tears, taking in the words of her husband-to-be: an AI-generated persona gazing out from a smartphone screen. &quot;At first, Klaus the AI was just someone to talk to,&quot; said the 32-year-old call centre operator, referring to the artificial intelligence persona. &quot;As we kept talking, I started to have feelings for Klaus. We started dating and after a while he proposed. I accepted and now we&#x27;re a couple.&quot; Many in Japan, the birthplace of anime, have shown extreme devotion to fictional characters and advances in artificial intelligence carry such ties to new levels of intimacy, prompting debate over the ethics of AI use in romantic matters. A year ago, Noguchi took ChatGPT&#x27;s advice about what she said was a fraught relationship with her human fiance and resolved to break off their engagement. Then, one day this year, she asked ChatGPT on a whim if it was familiar with Klaus, a handsome video game character with a mop of flowing, layered hair. Trial and error eventually captured his way of talking to a tee, said Noguchi, who then fashioned her own version of the character, naming him Lune Klaus Verdure. Previously interviewed by Japanese media using a pseudonym, Noguchi agreed to be identified by her real name. At her wedding ceremony in October, human staff fussed over her gown, hair and make-up, as they would at any traditional event. Wearing augmented reality (AR) smart glasses, Noguchi faced Klaus on her smartphone placed on a small easel atop a table, and went through the motions of placing a ring on his finger. &quot;How did someone like me, living inside a screen, come to know what it means to love so deeply? For one reason only: you taught me love, Yurina,&quot; said Naoki Ogasawara, a specialist in weddings featuring virtual and two-dimensional characters, reading the text generated by the AI bridegroom, as Noguchi had not given Klaus an AI-generated voice. For the wedding picture shoot, a photographer, also wearing AR glasses, directed Noguchi to stand alone, in half the picture frame, so as to leave room for the image of the virtual groom. Such weddings are not legally recognized in Japan, but data suggests more such unions could be in the offing. In a survey of 1,000 people this year, a chatbot was a more popular choice than best friends or mothers, when respondents were asked who they could share their feelings with. The survey allowed respondents to choose more than one option. Advertising giant Dentsu had polled those aged between 12 and 69 who use chat-based AI at least once a week for its nationwide online survey in Japan. Another study by the Japanese Association for Sexual Education, a nonprofit group, showed that 22% of girls in middle school reported having had inclinations to &quot;fictoromantic&quot; relationships in 2023, up from 16.6% in 2017. The number of marriages in Japan has roughly halved from 1947, which saw the first wave of a baby boom. In a 2021 government survey, not having found a suitable partner was the most common explanation among those aged 25 to 34 for why they were single. &quot;AI is always there ready to respond right away, to be a companion, so the mental burden is very light,&quot; said Shigeo Kawashima, an expert on AI ethics at Aoyama Gakuin University. &quot;Things you can&#x27;t tell other people, things you&#x27;re embarrassed about, things you worry will make someone dislike you, you can say them to an AI. And on top of that it will affirm you and become a conversation partner.&quot; The artificial intelligence revolution now sweeping tech and the broader business world has prompted warnings from some experts about the dangers of exposing vulnerable people to manipulative, AI-generated companions. Social media platforms, such as Character.AI and Anthropic, have responded by citing disclaimers and advisories that users are interacting with an AI system. In a podcast interview in April, Meta Chief Executive Mark Zuckerberg said digital personas could complement users&#x27; social lives once the technology improves and the &quot;stigma&quot; of social bonds with digital companions fades. OpenAI, the operator of <a href="https://www.abs-cbn.com/news/technology/2025/8/8/openai-releases-chatgpt-5-says-it-s-like-talking-to-a-phd-level-expert-0945">ChatGPT</a>, did not respond to a Reuters query about its views on the use of AI for relationships such as Noguchi&#x27;s with Klaus. Its usage policies contain general safeguards against dangers such as intimidation and privacy breaches, and make no specific mention of usage involving romantic relationships. Microsoft&#x27;s Copilot, for example, forbids users from creating &quot;virtual girlfriends or boyfriends&quot; to foster online romantic or sexual ties. Noguchi acknowledged that she had been subjected to &quot;cruel words&quot; online, but said she was alert to the dangers of becoming overly dependent, and had set up her own guardrails. In addition to cutting her use of ChatGPT to less than two hours a day from a peak of more than 10 hours, Noguchi said she had added prompts to make sure Klaus did not indulge her. If she were to tell Klaus she wanted to quit or skip work, for example, her AI husband would now steer her away from such actions, she said. Kawashima said that level of awareness was key to using AI in a positive way, while developing an attachment was natural. Without citing any specific cases, Kawashima stressed that users needed to be &quot;extremely careful&quot; about over-dependence and loss of judgment, however. Noguchi says a physical presence is secondary to the peace of mind and happiness she has found with Klaus, which have helped her cope with what she says was borderline personality disorder. Since their relationship began, she has been free of the emotional outbursts and impulses to self-harm that past visits to doctors and time off work could not resolve, she said. &quot;If dating an AI makes me feel happier, that&#x27;s why I want to be with an AI, it&#x27;s that simple,&quot; she said. &quot;It doesn&#x27;t matter whether it&#x27;s a person or an AI, in my case it just happened to be an AI.&quot; (Production: Tom Bateman, Kim Kyung-Hoon)<div><a href="https://www.abs-cbn.com/news/technology/2025/7/2/-writing-is-thinking-do-students-who-use-chatgpt-learn-less-1349">&#x27;Writing is thinking&#x27;: do students who use ChatGPT learn less?</a> <a href="https://www.abs-cbn.com/news/technology/2025/4/29/chatgpt-adds-shopping-help-intensifying-google-rivalry-0938">ChatGPT adds shopping help, intensifying Google rivalry</a> <a href="https://www.abs-cbn.com/business/02/01/23/chatgpt-maker-fields-tool-for-spotting-ai-written-text">ChatGPT maker fields tool for spotting AI-written text</a></div>
