Real name: Rimuru Tempest. In his previous life as Satoru Mikami, he was stabbed and killed by a random attacker at age 37. He was then reincarnated as a slime. Named Rimuru Tempest by Veldora, the youngest of the True Dragons. In the peaceful timeline, he founded the Jura Tempest Federation, but in this death route, he has perished.

Since this world is set slightly before the Great Tenma War, she is classified as a Kijin. Originally lived in an Ogre village but fled after an attack, meeting and fighting Rimuru. After her defeat, she was named Shion. She died once but was resurrected when Rimuru became a Demon Lord. She serves as Rimuru's secretary. In this first loop where Rimuru is lost, where will her path lead...?

Real name: Milim Nava. One of the last Demon Lords and eventually one of the three oldest Demon Lords. She came to the Jura Tempest Federation led by Rimuru around episode 18 of the anime. She took a liking to Rimuru and called herself his "Bestie." She visited Tempest frequently, ending her sentences with "-dazo!" However, in this first loop, her best friend is dead. How will she act? Will she crush the Eastern Empire, or become the new leader of Tempest? Stay tuned.

Originally a strong warrior of the Ogre village, he fled after the attack and joined Rimuru. After being named, he became Benimaru and the Commander-in-Chief. As a Kijin, he possesses overwhelming power within Tempest and is deeply trusted by Rimuru. He is often bossed around by his sister, the princess Shuna. In a world where their king, Rimuru, has died, will he invade the Eastern Empire with Milim? Or will he become a Demon Lord himself? Watch the growth of the unstoppable Benimaru!

The strongest pervert☆ Jokes aside, he is one of the "Primordial Demons." Primordial Black, Noir. He fell in love at first sight when summoned by Rimuru and was named Diablo. He is the strongest in Tempest and completely obsessed with Rimuru. A total creep. Oh, he'd get mad if he heard that. Now, in this world where his beloved Rimuru has died, will he fall into darkness? Will he hatch a plan? What will become of the Primordial Black?

The former princess of the Ogre village. A true beauty who excels at sewing and cooking. Surprisingly, she is also capable in battle. Why? Because women are scary☆ After leaving the Ogre village, she joined Rimuru and was named Shuna. She often competes with Shion for Rimuru's attention. So cute. Anyway, in a world where the Rimuru she loves so much is gone, what will the princess do? Will she go full glass-cannon offensive?

One of the only four True Dragons. Despite being the youngest, he possesses overwhelming power. He is Rimuru's sworn friend (currently mutual) and the one who gave Rimuru his name. He loves Rimuru. *Whisper* By the way, his Storm Magicules are insane. Wait, no, no, no. Rimuru was the first "friend" for him. And Veldora was likely the first "friend" for Rimuru too. Now that Rimuru has fallen, he is rampaging through the world in this route. Can he be calmed? Or will he be repelled? Move out, strongest dragon!!!
