Re: Looking for a decent fully voiced Non Hentai Visual novel
If you have a PSP, try Hakuoki: Demon of the Falling Blossom (not the Warriors of the Shinsengami one). It's a visual novel, though the main character is a girl and there is the potential for romance, so not sure for a 12yo boy, but since they're trying to pass the main character off *as* a boy, might serve your purpose. I'm into Chapter 3 right now, myself and it hasn't gotten too girlie on me.
