A term for a person who is loving and caring to someone they like until their love, admiration and devotion becomes feisty and mentally destructive in nature through over protectiveness, violence, brutality or all three combined. Yandere is mentally unstable and uses extreme violence or brutality as an outlet for their emotions.

Simply put, a yandere is lovesick; someone who has been driven to insanity by extreme obsession or love, thus resulting in abnormal behaviour if not violence. Take the tropes "Love Makes You Crazy", "Love Makes You Evil", "Love Hungry" and "Stalker with a Crush", turn them all up to eleven, and condense everything into a singular personified character archetype
