How much do you know about Yandere? This page will teach you everything you need to know.
The Yandere (ヤンデレ) type refers to a character who starts out nice and sweet but eventually becomes dark and obsessive over the one they love. They become stalkers and use violence on, and possibly even murder, any person who gets close to their love interest — even if they’re too shy to simply speak with that person they have a crush on.
This word is an abbreviation of Yanderu (やんでる) which means to be mentally or emotionally ill and Deredere (デレデレ) which means lovey dovey.
And that should answer the question “What is Yandere?” You can find more information on subcultures and terms just like this in my growing Otaku Encyclopedia, including all other -Dere types!
