In this world there exist spiritual pathways called Gates, that draw in the souls of the departed and move them to a new realm of existence. However, at times a Black Gate appears, and the Black Gate does not wait for death but instead forcefully sucks the souls out of living humans! Senju is a "Mitedamashi," an agent with the power to summon or seal Gates and save people's souls. He is guardian to Hijiri, a boy whose life he once saved.
After Hijiri discovers his own hidden powers, he begins a journey of self-discovery during which the distant past comes back to haunt him and his choices determine life and death, not only for those he cares about, but the whole world!
