Tensei shitara Slime Datta Ken - episode 17 - 28 Jan, 2019

Vesta succeeds in developing a full potion to equal Rimuru's potions, prompting Rimuru to attempt negotiations to develop low potions in Tempest. Just then, Phobio, beastkeeper of the demon lord Carrion, comes to Tempest with the intent of taking it over, but is promptly dealt with by Milim before Rimuru resolves things peacefully. Offering Milim a new weapon in exchange for information, Rimuru learns that the other demon lords have their sights set on him for foiling their plan to create a puppet demon lord. Later, the Border Survey Corps led by a man named Youm, joined Eren's party, come to Tempest, where Rimuru asks them to take credit for defeating the Orc Lord. Meanwhile, the demon lord Clayman takes an interest in a powerful beast known as Charybdis and sends Tear the harlequin to investigate. (Source: Wikipedia)
