Story sequence
Rimuru uses Beelzebuth to consume controlled Veldora, not to erase him but to bring his information into the protected inner space where Ciel can remove domination. The same approach is applied to Velgrynd after her parallel bodies and defenses are isolated.
Processing True Dragon energy and information transforms Rimuru's existence into an Ultimate Slime, a draconic demonic slime comparable in nature to the True Dragon race. The evolution explains why his magicule capacity and recovery cease obeying earlier Demon Lord limits.
Ciel combines Beelzebuth, Raphael's remaining systems, Veldora, Velgrynd, and spatial abilities into Void God Azathoth. Skill-creation functions are organized into Harvest King Shub-Niggurath, which stores skill information and supports the evolution of allies.
Veldora is released free of control. Velgrynd learns that Rudra's original soul has scattered and begins a journey through worlds and eras to gather its fragments, rather than continue serving Michael's imitation.
Motivations
- Rimuru refuses any solution that treats Veldora or Velgrynd as expendable energy.
- Ciel seeks the most efficient skill architecture for protecting Rimuru and the soul-linked nation.
Outcome
Both True Dragons are freed; Rimuru evolves to True Dragon-class existence and gains Azathoth and Shub-Niggurath.
Consequences
- Michael loses the empire and two crucial controlled assets.
- Rimuru can release and restore True Dragon partners from his internal world, creating extraordinary energy and survival redundancy.
Rimuru crosses from a powerful Demon Lord into the same existential category as the world's foundational dragons.
