Yuno Gasai was voted the most popular Yandere character of all time as of 2013
Rumors of a Mirai Nikki anime series began in early 2008 with Kôichi Mashimo, Yôsuke Kuroda and Yuki Kajiura being attached.
In the English Dub of episode 15, 'Dual Holders/Dual Cell Phones' there is a mistake in which Yuno tells Yuki that she will pretend to be Yuki's Boyfriend just like before, instead of Yuki's Girlfriend.
