Mei Mei Walk

Two anime characters stand on a dark, curved railway track in a tunnel, one with white hair and a long coat, the other with light blue hair and a school uniform, as the camera moves closer to the blue-haired character. The scene cuts to a close-up of the blue-haired character's face, then to a dark silhouette, followed by a bright flash of light, and finally reveals the character from behind, holding a wooden baton in a dark, illuminated space.
