Story
The world is filled with supernatural objects that house distortions of the world called “Vanits.” Shin Karamori wields one such artifact—an azure sword that granted his wish to live and gave him incredible combat abilities yet curses all those around him. Karamori throws himself body and soul into fighting bloody battles involving Vanits, accompanied by an artificial young girl named Archive, whose fate is dictated by a certain book. Karamori fights to save an important figure from his past, and he'll do anything to make it happen, even if that means Archive losing her life.
