His two-dimensional lover is modeled after a doe-eyed 16-year-old girl with blue pigtails who was created by music tech company Crypton. Miku has sold out 3-D concerts across Asia as well as a 2016 concert in NYC, The Post reported.

Kondo interacts with Miku through a $2,800 desktop device, where she shows up as a moving, talking image.

Even though his own mother didn’t attend the wedding, Kondo recently dropped about $17,600 on a formal ceremony at a local hall. Miku was present in the form of a stuffed doll with a wedding ring on her wrist.

Gatebox, the company that produces the holograms, issued a “marriage certificate” acknowledging their union goes “beyond dimensions,” since their relationship isn’t recognized by the state.

Kondo said Gatebox has issued more than 3,700 certificates to other “cross-dimension” couples.
