Top 5 yanderes

#5. Lucy/Nyu, Elfen Lied.

Never finished her show because lack of merchandise and also it was kinda boring... Still one of the most notable yandere out there

#4. Kaede Fuyou, Shuffle (The anime).

For the most part she was a secondary character with zero personality. Then at around episode 18 she got her backstory shown and did what she did to Asa. Pretty cool yandere and has some merch 

Honorable mention: Rena Ryuugu, Higurashi

Now, from what I've heard. Rena is more of a yangire instead of a yandere. But personally, idgaf so consider this a second third place or smth

#3. Yuno Gasai, The Future Diary.

Holy shit Future Diary was sooooo fucking bad. Yuno was the only girl that saved it even if she was hella annoying sometimes. Also she has like NO merch despite being arguably the most popular yandere???

#2. Sekai Saionji, School Days.

Of course School Days was gonna be #2. She stole her friend's man, got pregnant AND got cheated on/dumped by him. It was kinda reasonable for her to do what she did.

#1. Kotonoha Katsura, School Days.

Of course School Days was gonna be #1. Just watch School Days because you'll understand why she's the best girl
