On this episode, Ainz gathers his floor guardians and makes a plan with them. Later, he explores more on his surroundings.
It's quite cool to see Ainz thinking up his goals and what's he going to do next along with the floor guardians. Also they revealed a bit more about the floor guardians themselves and their personalities. Other than that, I wonder when Ainz and his forces will engage a battle. Now what's going to happen next? Overall, more nice build up and character details.
Conclusion: More nice build up and character details.
