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.

Shirotsugh "Shiro" Lhadatt may be a cadet in the Kingdom of Honneamise's Royal Space Force (RSF), but he has never been in space before—in fact, nobody has. The RSF is often regarded as a failure both by the country's citizens and a government more interested in precipitating a war with a neighboring country than scientific achievement. Following the funeral of a fellow cadet, an unmotivated Shiro is walking in the city one night, when he bumps into Riquinni Nonderaiko, a young, pious woman, genuinely enthusiastic about the significance of space exploration. As the two gradually bond, Riquinni's encouragement inspires Shiro to volunteer as a pilot for a prospective rocket ship, potentially becoming Honneamise's first man in space. Shiro and the RSF are soon joined by a team of elderly but eager scientists and engineers, and together, they embark on a mission to mold their nation's space program into a success. However, their efforts soon catch the attention of the government, which seems to have a different plan for the RSF in mind. Even as the odds are stacked against them, these men and women continue to stubbornly look to the sky, because somewhere among the frontiers of space may lie humanity's last chance at redemption.
