A portmanteau of two Japanese words. The first is yanderu, which means "to be sick," and the second is deredere, used here for "lovestruck." A yandere is often sweet, caring, and innocent before switching into someone who displays an extreme, often violent or psychotic, level of devotion to a love interest.
