Fujishima Kousuke (author of You're Under Arrest and OMG/AMS, plus also a prolific character designer for the Tales series) shotgun-married Otogi Nekomu (cosplayer who have also cosplayed as Peorth among others) back in 2016.
A bitter ex was apparently involved and sued him for mental anguish a year later. The law suit, is, IIRC, still ongoing.
He also had a ex-wife and adult daughter (who's younger than Otogi) from a previous marriage (divorced in 2014), and was allegedly in a 15-year cohabitating relationship/13-year affair with the aforementioned bitter ex.
