Overlord Episode 4 English Subbed Episode Title:Ruler of Death.Episode Description:Nigun Grid Luin, the captain of the Sunlight Scripture of the Slane Theocracy marches on Carne Village with a team of magic casters to kill Gazef. Realizing this, Gazef attempts to convince Ainz Ooal Gown (Momonga's new name) to defend the village to no avail, so he sets out with his men to confront them while Ainz assists the villagers in escaping. Gazef and his men fight bravely, but they are beaten severely by Nigun's men. Before Nigun's magic casters can deal the final blow, an item that Ainz had previously given Gazef activates and swaps the latter and his men with Ainz and Albedo. Ainz reveals that his whole scheme was to test the power that the Slane Theocracy's men had, and that he was using Gazef to do so. Immediately, Ainz begins effortlessly batting away the attacks of Nigun's men, much to their shock. This leads Nigun to activate a 7th tier spell, summoning a powerful angel to attack Ainz. The attack barely inflicts pain on Ainz, which he scoffs about. Albedo, however, is infuriated that someone hurt her "beloved" Ainz and threatens to massacre them. Ainz calms her down, and then proceeds to obliterate the angel with a black hole. Dumbfounded and horrified at the power Ainz displayed, Nigun begins to beg for his life. Laughing, Ainz responds by quoting one of Nigun's previous statements. After the battle, Ainz returns to Nazarick to announce his name change and their goal of spreading his new name, Ainz Ooal Gown, across these new lands. However, his servants misinterpret this as a declaration that he wishes to rule the world.
