The story centers around a guy (do we know his name?) who is the last remaining player (?) in the online game YGGDRASIL. His alter ego is Momonga, later Ainz Ooal Gown, a powerful undead Necromancer and also the guildmaster of the successful guild Great Tomb of Nazarick. The other members have already left the game long ago, but left him with their belongings and also the personal created NPCs, which serve as guardians of the Tomb (guild hall).
Like other people already wrote the story takes some time to get going, probably even another season, nevertheless is interesting.
It starts like this: On the day the game is supposed to shut down, Momonga can't log off - he is trapped (how original). Now everything centers around managing the guild and helping NPCs while finding out why he's trapped and if there are others like him.
Personally i think the characters are the shows weakest point owed to the 13-episode size. We have the player, the vampire gothic loli Shalltear (who the fuck designed her vampire form?!) and the submassiv loving demon girl Albedo - the rest isn't worth mentioning in fact apart from the battle maid Narberal you won't see much of them. Character development ? Nope.
The show ends with this typical "pressed content preview", you know that one were they lay the rootes for a 2nd season without promising anything. If it doesn't get one i probably wouldn't watch it again - let's hope it sells well
