The announcement of the upcoming event that will bring together several Demon Lords serves as part of the plan to face Clayman. But before that, Rimuru must find a way to save the people of Eurazania, who have become the target of a diabolical plot by Clayman.

Benimaru is in command of the troops that will face Clayman's army, which invaded the Animal Kingdom. If everything goes according to plan, achieving victory is just a matter of time.
