The story is set in Hell, and sees our protagonist, an oni named 8246 (Yatsushiro) making ends meet as a guide for the departed. That changes one day when he meets Tomori, a recently deceased girl. With her, he stages an outrageous plan to break out of poverty at all costs. But the chaos the two end up unleashing in their ill-fated get-rich-quick scheme threatens to shake the very foundation of Hell itself...
