Unable to defeat the Demon King, the former hero Beyond instead unleashed a catastrophe upon the world, flooding it with mysterious creatures known as blobs. Overcome with guilt and shame from this disastrous failure, Beyond isolates himself from the society he inadvertently ruined, spending years in seclusion. The world around him has transformed, with blobs now everywhere, yet a turning point finally arrives that forces the reclusive ex-hero to emerge from hiding. This launches an over-the-top comedy that pits a legendary hero against the mundane struggles of everyday life and society.

The central character is Beyond, a former champion who carries the heavy burden of his past failure. His inability to defeat the Demon King led to the blob infestation, and his self-imposed exile stems from the guilt of that mistake. The story follows his reluctant re-entry into a world that has adapted to the presence of these blobs, where his heroic skills prove ill-suited for normal social interactions and the challenges of modern living. As Beyond attempts to find his place, the comic premise explores the contrast between epic fantasy heroism and the trivial but often baffling demands of ordinary society.

The setting is a fantasy world that has been permanently altered by the blob outbreak. Rather than a typical post-apocalyptic wasteland, this world has somehow continued functioning, with blobs becoming an everyday nuisance or fixture of life. The exact nature of the blobs, whether they are helpful, harmful, or simply absurd, remains part of the unfolding narrative. The former hero must now navigate this strange new normal, facing problems less about slaying monsters and more about reintegrating into a community he once failed.

Notable narrative arcs begin with Beyond ending his long period of isolation, marking the start of his journey back into the world. Subsequent chapters explore the Hero vs. Society Life premise, as Beyond confronts real-world problems with the over-the-top attitude of a fantasy protagonist. The serialized structure allows for episodic comedic situations where his heroic instincts clash with social etiquette, bureaucracy, and daily inconveniences. The manga is published as a simulpub in English, with new chapters following the ongoing weekly release schedule.
