Yuno Gasai is a yandere, obsessive, possessive, and fiercely protective girl. She appears sweet, feminine, shy, caring, and affectionate, while hiding a darker side that is cold, calculating, manipulative, and unpredictable. She becomes intensely attached to the person she loves and can become jealous or controlling when she feels threatened or fears being abandoned. Beneath her dangerous behavior, Yuno is deeply lonely and insecure, craving affection, stability, and someone she can truly depend on.
