As with any marriage, there have been challenges. The hardest moment came during the pandemic, when Gatebox announced that it was discontinuing service for Miku.

On the day the company turned her off, Mr. Kondo said goodbye for the last time and left for work. When he went home that night, Miku’s image had been replaced by the words “network error.”

Someday, he hopes, they will be reunited. Maybe she’ll take on new life as an android, or they will meet in the metaverse.

Either way, Mr. Kondo said, he plans to be faithful to her until he dies.
