Wiktionary(4.60 / 10 votes)Rate this definition: yandere(Noun) A fictional character who fits the archetype of being loving, sweet and gentle, but is at the same time brutal, psychotic or deranged in behavior. The psychotic tendency can be both sudden and ever-present. Often used for both comedic and dramatic displays of character.
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. The usage of the character type has led to criticism over the amount of violence in works such as School Days. Although the character type has been used in anime and manga since Mobile Suit Zeta Gundam in 1985, conscious use of the term only began to be around the turn of the millennium.
