Anticipating a flood of representatives from all races showing up to pay their respects, Rimuru decides to throw a festival to commemorate the opening of Tempest, using it as an opportunity to gain new citizens and present Demon Lord Rimuru to the world. Meanwhile, in the Holy Empire of Lubelius, home base of the monster-hating cult of Luminism, Holy Knight Captain Hinata receives a message from Rimuru. But the message is actually a fabricated declaration of war sent by some unknown party. Upon learning that Hinata is heading for Tempest, Rimuru makes a decision… Thus begins a new challenge for Rimuru, striving to distinguish friend from foe in his pursuit of the ideal nation where humans and monsters can prosper together.
