In Episode 5 of The Aristocrat's Otherworldly Adventure: Serving Gods Who Go Too Far, Cain faces a series of challenges related to his new mansion. The episode begins with Cain's friends and family marveling at the transformation he has achieved using his powerful magical abilities. They are particularly impressed by the mounted red dragon, a rare and expensive decoration that Cain himself defeated.

Cain learns that, as a noble, he is expected to host a housewarming party. He decides to tackle this task with his own unique brand of hospitality, crafting handmade glasses as gifts and preparing a delicious meal, including the mouthwatering hamburger steak. Cain also introduces a new type of toilet that flushes with water, much to the amusement and delight of his guests.

Throughout the party, Cain even impresses the king with his thoughtful gestures and is praised for his "ultimate hospitality." However, not all guests are so easily satisfied. The arrogant Marquis Corgino shows up and initially mocks Cain's efforts, but eventually succumbs to the temptations of the delicious food and unique gifts. Though he demands more than his fair share, Cain skillfully handles the situation, leaving the Marquis momentarily speechless.
