A group of anime characters, including a large red robot, run across a rocky landscape from left to right, then stop and face forward in a confrontational stance. The scene cuts to a close-up of a character's eyes, then to a glowing purple rift in the ground, before returning to the characters in a battle-ready formation. The sequence ends with a close-up of a blonde character with X's for eyes, indicating they are knocked out. The setting is a desolate, rocky terrain under a dark sky.
