Arc 6The Dead Apostle Civil War
Aozaki Touko completed the Third Magic, allied with Altrouge, and confronted the Dead Apostles who sought to destroy her. After Touko defeated Crimson Lord and ended the civil war, Altrouge took control of his faction while Touko pursued her plans for a new life system.

- Crimson Lord gathered allies against Altrouge, while Arcueid joined the opposition before changing sides after learning her sister was pregnant.
- Touko drew the Dead Apostles and their forces into her Eternal Doll Kingdom and challenged Crimson Lord, defeating him after he unleashed his full power.
- Nero Chaos surrendered to Touko, other Dead Apostles gave up, and Altrouge took control of Crimson Lord's defeated faction.
