Watch Shakugan no Shana: Season III Online

Crimson Denizens and Rinne, beings from a parallel world, seek to devour humans' precious existences. To restore the delicate balance of the world, Flame Hazes hunt these entities down. Yet such things are unknown to Yuuji Sakai, who starts his day like any other and heads to school. His day, however, takes a turn for the extraordinary when he witnesses everyone around him freeze in place and is left the only one able to move. Immediately, a Rinne begins devouring the souls of those around him, but as the creature sets its sights on Yuuji, a katana-wielding Flame Haze with blazing red hair saves him. After his protector fixes the damage done, she explains why Yuuji was able to move: he has become a Torch, a remnant of a dead human being that will eventually fade from memory. Furthermore, he is also a Mystes, a Torch that houses an unknown treasure. Before his flame burns out completely, a Crimson Denizen will try to seize the treasure he holds, so the fiery hunter decides to watch over him. As Yuuji comes to terms with being dead, he resolves to live his life the best he can with the time he has remaining. [Written by MAL Rewrite]

Denizens from the Crimson Realm continue to infiltrate Misaki City and steal life energy from humans. To combat this threat, Flame Hazes are tasked with saving humans from losing their existences. But while it is a Flame Haze's duty to protect humans, Shana—the "Flame-Haired Burning-Eyed Hunter"—seems to be focusing her attention on one human in particular: Yuuji Sakai, a teenage boy who was unwittingly dragged into the fight between Crimson Denizens and Flame Hazes. Since her first encounter with Yuuji, Shana has started to see him as more than just a friend. In fact, Yuuji wonders if Shana might have revealed her feelings to him once before, but it is difficult for him to confirm due to her hot-and-cold personality. Nonetheless, their days pass like any other, until a new transfer student arrives at their high school—one who bears a striking resemblance to an old enemy. Yuuji and Shana have no time to dance around their feelings for each other; while their adversaries from the Bal Masqué organization plan their next attack, the two must keep their guard up as they explore the origin behind the coveted magical object within Yuuji's body, the "Midnight Lost Child."

The world has become a slaughtering ground for the Crimson Denizens, mysterious beings from a parallel universe who thrive on the life energy of humans. These merciless murderers only leave behind scant remainders of souls called "Torches," which are mere residues that will eventually be destroyed, along with the very fact of the victims' existence from the minds of the living. In an ambitious endeavor to put an end to this invisible, hungry massacre, warriors called Flame Hazes relentlessly fight these monsters. One fateful day, Yuuji Sakai ceases to be a regular high schooler—he becomes trapped in a crevice of time and is suddenly attacked by a Denizen. Coming to his rescue just in the nick of time is a nameless hunter who seems no different from an ordinary young girl except for her blazing eyes and burning crimson hair. However, before Yuuji can learn anything more about his situation, he discovers that he has already been reduced to a Torch—merely a scrap of memory waiting to be extinguished.
