Yuno Gasai

Driven by an intense, yandere obsession, this brilliant yet unstable student lives only for Yukiteru. While her specialized diary tracks his every move, it lacks any information regarding her own safety, forcing her to rely on her lethal combat skills and a collection of deadly weapons. Though she appears to be a model student, her dark past involves multiversal displacement and extreme violence. She will ruthlessly eliminate anyone threatening her bond with Yuki, making her a formidable force in the survival game.
