Haruomi Io is a withdrawn high school student burdened by profound grief following the tragic deaths of his mother, younger sister, and childhood friend. Struggling to find meaning or connection in his daily life, he drifts through his routine with little interest in the world around him. However, his quiet despair is abruptly shattered when he becomes the target of a violent, gun-wielding faction known as the Seventh Gospel Organization. Suddenly thrust into a dangerous conflict he never sought, Haruomi finds an unlikely protector in Zilch, a powerful demoness who steps in to aid him. Yet her assistance comes with its own complications, as her unpredictable nature proves to be just as overwhelming as the enemies pursuing him. Forced out of his emotional numbness by this sudden collision of gunfire and dark magic, Haruomi must navigate a chaotic new reality. Surrounded by supernatural forces and striking companions, he begins to confront the apathy that has defined his existence, discovering that surviving this bizarre war might finally give him a reason to engage with life once more.
