The episode begins in Babylon, a hub where various warriors gather, including mercenaries and former Holy Knights. Among them is Alistair from the north, who offers his services to Lady Roxy, the heiress of one of the five great families. Roxy is determined to follow in her father's footsteps and protect her people from monster attacks.

Fate and Greed explore Babylon in search of a scabbard for their sword. They encounter Jade, a skilled craftsman, who offers to make a custom scabbard for them. However, the price of 500 gold coins is steep, so Fate looks for ways to earn more money. They venture into Galia, which is plagued by monsters. They encounter orcs and engage in a fierce battle, testing Fate's combat skills and Greed's magical abilities. Fate's ability, Gluttony, which usually activates after defeating enemies, remains inactive, leaving the two confused.

Upon returning to Babylon with their loot, Fate and Greed are confronted by other warriors who accuse them of theft. A confrontation ensues, during which Fate defends himself and receives 100 gold coins for the orc ears.

Jade Stratos, impressed by Fate's skills, proposes a partnership and offers Fate equipment that he can use as a form of advertisement in battle. Fate agrees, seeing it as a mutually beneficial arrangement.

Later, Fate meets Eris, who, like him, possesses the ability of a deadly sin. Eris shares her long-held knowledge with Fate and discusses the concept of aggression in monsters and humans. She prophesies Lady Roxy's death and hints that this will lead to the emergence of a powerful individual who will become a future pillar of the kingdom.

Despite Eris's arguments, Fate vehemently opposes Roxy's death and vows to protect her.
