just what is yandere ??

according to mr. wikipedia:
~Yandere (ヤンデレ?)
a Japanese term for a person who is initially very loving, caring, and gentle to someone (or at least innocent) they really, truly like and care for a lot before their romantic devotion becomes mentally destructive in nature, often through violence and/or brutality. The term is derived from the words yanderu (病んでる?) meaning a mental or emotional illness, and deredere (でれでれ?) meaning to show affection. Yandere characters are mentally unstable, and sometimes are incredibly deranged and are not mentally sane, often using extreme violence and/or brutality as an outlet for their emotions.

Some yandere characters that you might not know:
~ Rolo Lamperouge (Code Geass)
- can be considered a yandere for his ruthless devotion to the series protagonist Lelouch (who himself rises in arms against his father and his empire to create a better world for his little sister), as his affection grows to the point he will attempt to kill even those who are close to Lelouch in order to not be replaced

~Belarus from (Axis Powers Hetalia)

~ Hatsune Miku and Megurine Luka(vocaloids0 in the song "Scissorloid"
