Jigoku-san, a horned, fanged demon cloaked in coarse fur, serves as Hell’s envoy with a mandate to unleash pandemonium on Earth. Dispatched through a portal conjured by Chimimoryo spirits—diminutive, spherical entities bridging realms—he stumbles into the human world, unprepared for its routines and norms. Forced to navigate mundane chores and baffling social customs, he begrudgingly shelters in the Onigami sisters’ gardening shed, forging an uneasy alliance with them. The Chimimoryo, ever-present and mischief-prone, oscillate between enabling his infernal duties and anchoring him to his chaotic purpose. Yet his interactions with the sisters unravel unexpected layers: beneath his hellish bravado lies a conflicted soul, torn between innate destructive impulses and reluctant adaptability. Their capricious interventions derail his schemes, sparking absurd clashes that blur hostility and camaraderie. While his pre-earthly past remains shrouded, his journey hinges on reconciling demonic instincts with the trivialities of human coexistence. The Chimimoryo’s eerie vigilance and the sisters’ unyielding influence chip at his resolve, bending—but not breaking—his devotion to upheaval. His mission persists, a smoldering thread woven through the fragile tapestry of his evolving existence.
