3x14 - Shakugan no Shana

The Flame Haze army retreats as the Snake of the Festival destroys their morale. He announces his plan to create a new world, a complete copy of ours, to be a paradise for Tomogara and with Power of Existence flowing everywhere. Thus, all Tomogara would leave the world and the Flame Hazes would stop fighting agaist them. After that, panic and chaos reigns among the Flame Hazes, who now don't have a purpose and the Tomogara attack them.
