Mirai Nikki, Dead Tube Recommendations
Yandere , psychopathic main female character .
Mashiro Mai ( Dead tube ) & Yuno ( Mirai Nikki ) Both goes on killing people with no concern . Both of the Girls are CRAZY psychopath
Where main male character is innocent in that respect . Both mc gets dragged into something they can't imagine .
Both the series have a lot of killing and plot twist .
They are both good psychological thriller .
both have a "yandere" heroine
the heroines of each manga kill people without no care or concern, a bit crazy and only care about the protagonist
the protagonists seem innocent and are looped into something unimaginable
the protagonists are seen as good people until something happens to them ( what happens to them are very similar as well) and then they become despairful and only care about their goal.
Both series just involve a lot of killing/death
however i would say Death Tube is a LOT more gorey than future diary, and there are a LOT more sex scenes
