Sieg and Astolfo reunite and discover Sieg has Command Spells now, but are interrupted by Celenike. She uses her own Command Spells to force Astolfo to kill Sieg, but she herself is killed by Mordred before Astolfo can carry out the order. With Astolfo's master dead, Sieg makes a contract with Astolfo and becomes his new master. In the Hanging Gardens, Shiro tells Jeanne that he intends to use the Grail to bring salvation to humanity and will eliminate anybody in his way. Since Shiro possesses all of the Red Faction's Command Spells, Karna, Achilles, and Atalanta reluctantly stand down. Avicebron accepts Shiro's offer for surrender and joins his side, under the condition that Roche not be harmed. Jeanne and Chiron refuse to join Shiro, and are rescued when Morded arrive and creates a distraction, revealing that she and Sisigou have also decided to oppose Shiro. Back in the castle, Fiore, Caules, and Gordes confront the rescued homunculi when Sieg intervenes, intending to negotiate with the Black Faction by leveraging his status as Astolfo's master. Fiore is then interrupted by a report from Chiron warning her of Avicebron's betrayal. Roche, unaware of Avicebron switching sides, meets him by the lake, bringing a special item he requested.
