Animes with the main character being female. The story follows the female not the male.
Animes that you can show people when they complain that "Anime is so childish! It's for kids!"
(Without Ecchi/Film/OVA and shonen like Naruto/Bleach/One Piece)
A few on this list will have both male and female leads but I'll be focus img on the females
This list is about anime that are filled with the shedding of blood and some times guts.
This is my personal picks for a yandere anime, and it's not in a particular order either
