A foxy temptress. A strange misty tree demon. A girl with the power of the goddess Xianjia! Being caught between these women is a feat in it of itself, but our hero Feng Xi must fight in order to protect the peace and save the world!
Sakai Yuuji thought he was a normal high school student, until one fateful day when time stopped. Watching in horror, he witnesses a monster devouring the "frozen" people around him; but luckily for Yuuji, he is saved by a sword-wielding red-headed girl that calls herself a "Flame Haze". The girl informs him that he has been dead for some time now and that his current self is merely a replacement for the human that he used be while alive. He is, she says, merely a torch whose life will come to an end when the blue flame in his chest ceases to burn. After this rude awakening, Yuuji realizes that he is able to see the flames of life in other "torches"; and after discovering that a friend of his is also a torch -- and her life is burning out faster than his – he gains the courage to live out the rest of his life with meaning. Will Yuuji be able to find his place in the world before he ceases to exist?
High school life was just beginning for Yuuji Sakai, and while still growing accustomed to new classmates and teachers, a larger truth hit him. One day he found out that demons known as Guze no Tomogara were devouring human’s existence, unbeknownst to but a few. That was the day when he met Shana, a red-haired and blazing-eyed hunter of demons, and that day his life would change forever. She told him that he was just the fragment of a human, and that demons would hunt him for a strange gift he bore within him. Although discarding him as a nuisance at first, Shana comes to admire his resilience, and Yuuji finds new strength and determination. As the story unfolds, their relationship changes and both tempt their fates...
