Is there any cannibalism in Mirai Nikki (Future Dairy)? I'm trying to suggest Mirai Nikki (Future Dairy) to a friend but they really don't like cannibalism but they're cool with the killing and all that.

So is there any cannibalism in Mirai Nikki?
Having read the manga and watched the anime, I can say with some certainty that there is no cannibalism in Mirai Nikki.

Your friend might have suspected such thing due to the fanbase surrounding Mirai Nikki, which often creates AMV's and tributes using the song "Cannibal" by Kesha.
