name change

A black-haired anime girl with white horns and green eyes lies on her back against a blue sky, smiling and raising her right hand in a wave, then lowers it while looking at the camera; the scene cuts to a white screen with the text "code yunan," followed by a light green and black robot in a snowy, rocky environment, then a black screen with the text "agent xenon," and finally returns to the girl in the same pose but with a slightly different angle and expression.
