The Mirai Nikki Yandere Face, also known as the Yuno Face or Ecstasy Face, originates from the anime series Future Diary, specifically a scene where the protagonist Yuno Gasai promises to protect her love interest, Yuki. Her flushed cheeks, wide-eyed stare, and the way she cradles her face became the definitive visual representation of the yandere archetype—a character who is sweet but becomes homicidal or obsessively devoted. The image first gained massive traction on 2chan and 4chan around 2011, leading to countless traced fan art versions where other fictional characters were drawn in the same pose. Today, it remains the go-to template for expressing extreme obsession, creepy devotion, or overwhelming excitement over something niche.
