Yggdrasil is a Dive Massively Multiplayer Online Role Playing Game released in 2126 came to see its end after 12 years of standing as the top DMMO-RPG. Momonga, guildmaster of Ainz Ooal Gown, is conversing with Herohero during the last moments of YGGDRASIL. Herohero bids farewell to Momonga and logs out. Momonga is enraged about his friends leaving the game, but cools down after noting that they didn’t abandon the guild – it was that they had real life issues to deal with. Still engrossed in the memories of the past, he takes the Staff of Ainz Ooal Gown before heading to the throne room. On the way he ordered Sebas and his battle maids to follow and met Albedo there. After checking her setting Momonga (on a whim) changed it to fall in love with him as its originally setting created by Tabula was that she was an absolute “bitch”. Momonga closed his eyes to await the forced logout by server but realized something was wrong since he was still in the game. He discovers, to his astonishment that his servants have developed their own personalities and can be directly communicated with. Albedo, in particular begins exhibiting the personality traits based on the settings Momonga had set, much to his shock.
