Yuno of course. Classic yandere.
And holy crap, Rena, Lucy, and Flandre are not yanderes.
2 main qualifications of yanderes: crazy and in love.
Rena's not in love. Lucy's not crazy. Flandre's neither (maybe a bit crazy..). Rena isn't that crazy either, just superbly amazing at swinging a hatchet.
But haven't read either the Higurashi or Elfen Lied manga so, I'm judging by the anime. Fan culture does not count, sorry Flan-chan.
