In Episode 8, Fate and Myne continue their journey and reach Babylon, the city of the guardians. This city, known for its walls made of an unyielding alloy, has withstood the attacks of Galia's monsters for millennia.

The episode begins with a conversation between Fate and Myne about their recent experiences and the challenges they have faced. Myne, still struggling with her rage ability, is observed eating voraciously—a behavior that Fate humorously questions.

Soon after, they encounter Aaron Barbatos, the village chief they had met earlier, who now reveals himself as the lord of Hausen Castle. Aaron, a former hero, shares his past and his connection to Roxy Hart, another character they will meet. Roxy, a young holy knight, is on a mission in Gallia and is being trained by Aaron, who has a history with her family.

The episode progresses as Fate and Myne come across a chimera named Haniel. This chimera, a biological weapon of the Galian military, poses a significant challenge. It turns out that the chimera is in a larval stage, making it vulnerable yet still dangerous.

Fate and Myne engage in a fierce battle with Haniel. Myne orders Fate to use the soul-devouring aspect of his Gluttony ability to defeat the chimera. Despite the moral dilemma, Fate agrees, understanding the necessity of the action.

The episode reaches its climax as Fate and Myne succeed in defeating Haniel. However, the victory is bittersweet. Fate feels deep sorrow as he consumes the chimera's soul.

Afterward, Fate and Myne share a profound conversation. Fate asks Myne to kill him should he ever lose control of himself, which Myne seriously accepts. The episode ends with Fate and Myne parting ways, each going their own path.

During the battle, Fate and Myne demonstrate their combat skills and strategies. They employ a combination of magic and physical attacks to weaken Haniel. Fate uses his Gluttony ability to identify the chimera's weak point and target it precisely.
