A hand makes a peace sign as a blue and yellow pen spins in the air above it, then the scene cuts to a woman with long green hair in a school uniform performing a high kick in front of a chalkboard with Japanese text, followed by a man in a tuxedo speaking into a microphone in front of an audience, then a soldier in a helmet operating a machine gun on a battlefield with smoke and explosions in the background, and finally the title "BATTLEFIELD 1" appears in white letters against a dark, smoky background with red light flares.
