Bakom vår värld gömmer sig en annan: en värld med mäktiga och kraftfulla monster som våldsamt härskar över deras rike. När en oväntad sandstorm förflyttar Kapten Artemis och hennes trupp till en ny värld, blir soldaterna chockade över att upptäcka att den okända världen är hem till enorma och hotfulla monster som är immuna mot soldaternas vapen. Under deras desperata kamp för överlevnad, stöter truppen på den mystiska monsterjägaren Hunter, som med sina unika färdigheter lyckas vara ett steg före monsterna. När Artemis och Hunter sakta bygger upp ett samarbete, upptäcker hon att han är del av en annan trupp ledd av Admiral. När de möter en fara så stor att den kan förstöra världen, kombinerar de modiga krigarna sina färdigheter för att kämpa i den avgörande uppgörelsen.

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.

Shi Yi was once feared by men as a bloodthirsty demoness, killing hundreds. No one could stand in her way. But scared of the woman she'd become, Shi Yi's treasured blood slave Yi Ling stabbed her and imprisoned her in ice. Now 200 years later, Shi Yi is free from her prison but with no knowledge of who she is. Still plagued by blood rage when she uses her powers, she finds her way into the care of the seemingly familiar Hua Yu Tang, who promises to heal her from this mysterious ailment.
