Tensei shitara Slime Datta Ken - episode 10 - 03 Dec, 2018

Learning that the orcs who attacked the ogre village were being led by a masked majin, Rimuru proposes that the ogres join him as his subordinates. Agreeing to a temporary alliance until the orcs are defeated, Rimuru names the ogres Benimaru, Shuna, Shion, Hakurou, Souei, and Kurobe, evolving them into kijins. Meanwhile, the chieftain of the lizardmen, sensing an Orc Lord is controlling the thousands of orcs heading their way, sends his son, Gabiru, to enlist help from goblins. (Source: Wikipedia)
