Ore ga Akuma de, Aitsu ga Yome de

In the demon realm, it is a fundamental rule that demons may grant humans a single wish in exchange for their souls. Despite his boundless ambition, Anzam Nia has failed spectacularly at this task, collecting absolutely zero souls and plummeting to the very bottom of the demonic rankings. After being unceremoniously exiled to Earth by the authorities, he finds himself stranded in Japan. Desperate to secure a human contractor so he can finally return home, his path unexpectedly crosses with a lonely little girl. Mistaking him for an angel sent from Heaven, she insists on forming a contract with him, fully aware that granting her wish will cost her life. When Anzam Nia finally seals his first-ever pact, the girl’s impossible request leaves him stunned: she wishes for them to get married. Thus begins the blissful, utterly absurd married life of an adorable yet foolish couple. Bridging vast differences in race, age, and personality, their unconventional union marks the start of a heartwarming and chaotic domestic journey unlike any other.
