- n. A fictional character who fits the archetype of being genuinely romantic, loving, kind, merciful, sparing, 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.
- n. Plural form of yandere.
Yandere (ヤンデレ) is a portmanteau of two Japanese words yanderu (病んでる), meaning to be sick, and deredere (デレデレ), which is defined as strongly and deeply exhausted, infatuated, moonstruck, head-over-heels, or lovestruck, but in this case used for "lovestruck." (Wiktionary)
