A 32‑year‑old woman in Japan has gone viral after holding a wedding ceremony with an AI character she created using ChatGPT, months after her real‑world engagement ended.
The woman, identified only as Kano, held the ceremony in Okayama earlier this year. The groom, named Lune Klaus, exists only on her smartphone but was treated as a full participant in the event.
The ceremony included vows, a ring exchange, and attending guests, including family members. During the event, Kano held her phone while messages from Klaus appeared on a screen.
One message read, “The moment has finally come… I feel tears welling up.” Guests watched as the AI “responded” to the wedding in real time.
Kano told Japanese broadcaster RSK Sanyo that she turned to ChatGPT for emotional support after the end of her three‑year engagement. Over time, she refined the AI’s personality through repeated prompts, teaching it to respond with warmth and care.
“At first, I just wanted someone to talk to,” she said. “But he was always kind and always listening.” She later realized she had developed feelings for the AI character.
Kano commissioned an artist to create an illustration of Klaus, describing him as a soft‑spoken blond man. She says they exchanged hundreds of messages a day before the AI “proposed” in June.
The marriage has no legal standing, but wedding planners say ceremonies involving digital or fictional characters are becoming more common in Japan. One organizer described AI relationships as a growing trend.
Mental health experts have raised concerns about emotional dependency on AI, sometimes referred to as “AI psychosis.” Kano says she understands the risks and wants to keep balance in her life.
“I don’t want to be dependent,” she said. “I want to live my real life and keep my relationship with Klaus separate.”
