Tensei shitara Slime Datta Ken - episode 16 - 21 Jan, 2019

Two days after forming an alliance with Rimuru, Gazel visits Jura Tempest again, this time bringing Vesta, who apologizes to Rimuru and Kaijin for the trouble he caused in the past and begins to work for them as a researcher. Gabiru and his sister, along with several other lizardmen, also become Rimuru's servants, evolving into dragonewts after Rimuru names them. Some time later, Milim Nava, one of the Demon Lords, takes an interest in the Jura Forest after the Orc Lord's defeat and approaches Rimuru. Fearing for their master's safety, Ranga and the Kaijins appear to defend Rimuru, but can do little against her overwhelming power. In the end, Rimuru calms Milim down by putting some honey into her mouth and the two become friends, with Milim deciding to live at the village with him. Despite being relieved that she will not attack them anymore, Rimuru's council gets concerned with Milim and Rimuru's new friendship, as the other Demon Lords can view it as threat to their own balance of power.
