It's girls, gangs, and cars in this adaptation of the 1985 manga in Young Magazine, by Lullaby for Wednesday's Cinderella-creator Michiharu Kusunoki. Local punks steal cars, switch the plates, and sell them, but not without racing them for a while against rival gangs. The anime continues the story where the 1987 live-action movie starring Kazuya Kimura left off.

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. As Yuuji noticed a blue flame in his chest, she called him a “Torch”, a temporary replacement, saying that the “real” Yuuji’s existence had already ended. Unfazed, Yuuji befriended the strange girl, named her “Shana”, and joined her fight against Tomogara and other Flame Hazes.

He had thought his normal days would last forever, until they were ended abruptly by an encounter with a girl with red hair and eyes. He named her Shana. Not long after he enters high school, Sakai Yuji’s normal days come to an end. He sees something bizarre on his way home: people are frozen in a strange fire, and a monster that looks like a large doll is attacking them. Just when he's about to be killed, a girl in a dark cloak wielding a large sword appears, and slices the monster in half. Although Yuji survives the strange encounter, the girl informs him of a desolate truth: " 'You' don't exist anymore." She calls herself a Flame Haze who hunts "Guze no Tomogara"; intruders from another world. She explains to him that he is a "Torch", a substitute of Yuji whose “existence” has already been devoured. She also told him that he is a special Torch, "Mystes", which contains a precious item in it. When he looks at his chest, he sees within himself a faint flame, just as she said. It is in this way that his eternal struggle alongside the girl begins.
