And this one, (I don’t watch Naruto, just only know the name) She is more of a tsundere as much as I saw her.
And this one, but her lesbian magical time warping resetting girlfriend is even more yandere, and she has black hair. She is actually more of a Dandere, I guess, just like Flutters.
And the truth is, not every pink haired girls are yandere in general. But the hot color tone can affects a little.
Gamzee doesn’t really fit, since he was just drugged up on Sophor slime at first. After it wore off, he just got in touch with his Highblood rage.
But yeah, the other 2 fit.

You know what? You’re right.
BEWARE THE PINK-HAIRED GIRLS
Lucy doesn’t kill people with her mind. She kills them with her “vectors”, which are invisible hands that protrude from her back.
Other than that, yeah, this is a fitting comparison.
On a side note we need to expand that Elfen Lied tag.
But I don’t know any of them.
Except pone, of course.
