Shakugan no Shana III (Final)

Yuji disappeared the fateful night he was supposed to choose between a life combating evil by Shana's side or as a normal teenager. He returns from near-death to lead the Crimson Denizens in a dubious plot to bring peace to the universe, but Shana isn't fooled. In an explosive reunion, the fiery warrior faces her unlikeliest of foes while Flame Hazes from across the world join forces to ignite a war that will determine the fate of all supernatural kind. (Source: FUNimation)Sakai Yuuji, a high school student who expected his normal life to last forever, is dead. When he was on his way home he witnessed a shocking view as the world suddenly froze: people were engulfed by blue flames and a monster resembling a large doll swallowed them. Just as the monster prepared to consume Yuuji, a sword-wielding girl in black attire with flaming red eyes and hair that burns like embers saved him from the monster. The girl called herself a “Flame Haze” who hunts the “Guze no Tomogara”, creatures from another world.
