After centuries of demonic invasions, the hero Terios finally defeats the Demon King, bringing peace to the world before disappearing. But the supposedly dead ruler returns in an unexpected form: as a dog. Now a fluffy former Demon King, he tries to live peacefully while protecting his granddaughter, who has become a target for the entire world. His new life is devoted to keeping her safe and carrying out the deeds he left unfinished.
