They both involve a lot of violence and possesive yandere characters.
Where Mirai Nikki had a female lead be the yandere, Raise Wa Tanin Ga Li has the yandere being the male lead. Raise wa Tanin ga li, while involving a yandere within a heterosexual relationship during a violent enviornment, with their cast of very interesting characters allows you to be engaged in a relationship that's pretty self aware.
