The accident awakens the Beast of the Seal-Keroberos, nicknamed "Kero"-who tells Sakura that she has released the mystical "Clow Cards" created by the sorcerer Clow Reed. Ten-year-old Sakura Kinomoto is an ordinary fourth-grade student living in Tomoeda until, one day, she stumbles upon a mysterious book of cards titled "The Clow." Pondering over her discovery, she unintentionally causes a magical gust of wind to scatter the cards all over town. 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. 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. 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.

In an ambitious endeavor to put an end to this invisible, hungry massacre, warriors called Flame Hazes relentlessly fight these monsters. 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.

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.
