Mirai Nikki

A pink-haired woman with a gentle expression leans toward a dark-haired man, their faces nearly touching in a close-up, before the scene cuts to the man's horrified face covered in blood, then to the woman wielding an axe against a masked opponent on a bridge, and finally to her staring directly at the camera with a revolver in her mouth. The sequence takes place in a dimly lit, possibly ruined indoor setting, a dark outdoor environment, and a nighttime bridge, showing a progression from intimacy to violence.
