MOL: SAO

A character in a dark, ruined city fires a weapon at a large, mechanical enemy, causing it to explode and send debris flying. The scene cuts to a close-up of a determined young man with green hair aiming a rifle, then to a woman with long black hair reacting in shock as a glowing energy beam passes near her face. The sequence ends with a flying character wielding a purple sword attacking a green, glowing figure in a stormy, cloudy sky.
