Yandere

Summary

A yandere is a type of character in anime and manga characterised by being affectionate, becoming either possessive or obsessive. The term is a portmanteau of the words yanderu (病んでる), meaning ill, and deredere, meaning to show genuinely strong romantic affection. Yandere characters are often willing to go to extreme lengths to be with their lover, and have been said to be reminiscent of people with borderline personality disorder.
