The Tokyo Gull

A pale-skinned anime character with red eyes and a white outfit appears in a series of quick cuts, first shown with arms outstretched in a pink-lit room, then smiling with a hand to their face against a background of repeating text, followed by a silhouette leaping in a dark, purple-hued environment, a close-up of a wide-eyed, grinning face, a smiling character with black hair, and finally a mirrored image of two identical characters in uniform.
