I don’t see a problem with it. It’s really no different than getting inspiration and naming your child after a character in a book or a movie.
My brother has been playing the Kingdom Hearts games for years, and that’s where I first heard the names [name]Sora[/name] and [name]Kairi[/name]. Fell in love with them right away! Then I looked them up and fell in love with them even more (especially [name]Sora[/name]). I could see myself possibly using [name]Sora[/name] in the future.
