A black and white close-up of a girl with red eyes winks, then the scene cuts to a red-haired anime girl with a skull motif posing with the text "GROU ZERO," followed by a girl with black hair and red eyes with blood on her face and musical notes floating around her, then a girl in a dark hood making a hand gesture with a red light on her finger, then a close-up of a pink-haired girl singing into a microphone, and finally a group of five anime girls standing together against a white background.
