A bumbling wolf thrust into babysitting finds himself bound by absurd contracts across two worlds, accidentally thwarting cosmic schemes while managing a harem of powerful misfits. Ruben—once Ravenswood—embodies the archetype of a reluctant hero: formidable yet perpetually cursed by poor judgment. His constant entanglement in binding pacts stems from an unfortunate combination of gullibility and bad luck, transforming the fearsome Fenrir into an unwilling caretaker. His troubles begin when a Human ensnares him into a lifelong guardianship over Alicia, a mysterious figure concealing a dangerous Yandere nature. Desperate to escape the collapsing world of Gihon, Ruben encounters Pluto, who demands an impossible sacrifice—slaying THE Cthulhu—as the price of passage. The wolf agrees without comprehending the weight of his oath, propelling himself toward an apocalyptic confrontation. Upon reaching Pison, Ruben's misfortunes compound when Leviathan, the perverse Queen of the coast, defeats and binds him through a Master-servant pact while he remains unconscious. His journey continues through encounters with Jobina, the masochistic daughter of Job and one of the seven mortal powers, whose vendetta against Leviathan drives her to demand her own covenant with Ruben—adding another dependent to his burgeoning household. Each misstep inadvertently sabotages Sarvest's grand designs, forcing the antagonist to contend with an unworthy yet remarkably effective adversary. Compounding this chaos, Ruben crosses paths with God itself—an entertainment-obsessed teenager who exploits his compassion into yet another binding agreement. Combining action, adventure, and comedy, this tale weaves mythological beings, cosmic entities, and slice-of-life moments into a narrative where one wolf's attempts at simplicity spiral into legendary chaos and unexpected heroism.
