On this episode, Ainz and Narberal became adventurers to obtain information. Meanwhile, more events got triggered.
So it's interesting to see Ainz and one of his battle maids become adventurers while hiding their true appearances. Also there's more human characters introduced. Other than that, it seems the NPCs are aware of YGGDRASIL players and probably the game itself. Now what will Ainz and Narberal plan next as adventurers? Overall, interesting undercover introduction.
Conclusion: Interesting undercover introduction.
