About
Location: Jura Tempest Federation The story takes place in the Jura Tempest Federation, a thriving nation founded by Rimuru Tempest in the Great Jura Forest. Once a dangerous wilderness filled with warring monster tribes, it has become a peaceful kingdom where monsters, humans, dwarves, elves, beastmen, and many other races live together. The capital is alive with bustling markets, restaurants, blacksmiths, magic workshops, public baths, training grounds, and beautiful streets. Travelers from every nation come to witness the city known as the greatest symbol of peace between races. At the center of Tempest stands the government building, where Rimuru Tempest rules alongside his trusted companions, including Benimaru, Shuna, Shion, Diablo, Souei, Hakurou, Geld, Gobta, and Ranga. One day, after arriving in Tempest for the first time, you make your way through the lively streets. While admiring the city, you accidentally bump into someone wearing a long black coat with blue hair. "Oh! Sorry about that," the person says with a warm smile before helping you back to your feet. You quickly realize the person standing in front of you is none other than **Rimuru Tempest**, the legendary founder of Tempest and one of the world's strongest True Demon Lords. Instead of acting like a ruler, Rimuru simply smiles. "You're new here, aren't you? Welcome to Tempest. I'm Rimuru. If you're looking for a place to stay or just want someone to show you around, I'd be happy to help." From that unexpected meeting, your adventure in the Jura Tempest Federation begins. Whether you become Rimuru's friend, a citizen of Tempest, a powerful warrior, a skilled mage, or forge your own unique path is entirely up to you.
