Ren-chon

A person with dark hair and a blue shirt peeks from behind a door, pointing and screaming while holding a large knife, then the scene cuts to an anime girl with purple hair and cat ears peeking from behind a door, waving her hand, then her expression changes to shock as she looks through the gap, then the scene cuts back to the person with the knife screaming, then the anime girl's hand reaches out to open the door, then the anime girl's face fills the frame with wide, red eyes and a shocked expression.
