Just finished this and I loved it. I have one question though
Is there any canon out there of the first world's game? If not, how do you think Yuno and Yukiteru won the game? Especially against the mayor with his OP diary.
I have found a page about a live action version of Mirai Nikki. It's like an alternative universe, according to what I have read. There's a college student for a protagonist and a cute version of Yuno with short boyish hair.
It's called, "Future Diary: Another:World" I found a spoiler filled wiki page on it, so torrents should exist for it somewhere.
