I want them

A person with dark hair and a dark hooded garment peeks from behind a white door frame, pointing a finger forward, then reappears screaming while holding a large knife. An anime character with light purple hair and a red and orange outfit peeks from behind a door frame, raising a hand in a wave, then shows a surprised expression with wide eyes and an open mouth. The scenes alternate between the live-action person and the anime character, both positioned in doorways.
