A female anime character with long hair and a wide-brimmed hat wields a large, glowing red hammer, swinging it in a circular motion to create fiery rings while shouting "Explosion!" and "Let the hammer of eternity descend unto me!" as she battles an opponent in a dark, forested area. The scene cuts to a view of Earth from space, where a massive, bright explosion erupts on the planet's surface.
