that's blu-ray special volume 4 you've been trolled, and here's some spoilers on bd4

back during  YGGDRASIL days  heteromorphic players where being hunted down because there's a special class that can only be obtained after killing a certain number of  heteromorphic players. most  heteromorphic players restricted themself in 3 of the 9 world where  heteromorphic race have a ground advantage. the first nine lead by touch me ignore the dangers and advanture into human world where they do alot of pk, they called the team NINE'S OWN GOAL for the 9 point of experience they gave to other players to help them obtain the special class.

After the team grows in number and decided to form a new guild, they ask Momonga to be the guild master to prevent the team from getting split, because of a former argument that happened between  Ulbert, touch me and 1 other first nine, which cause 1 of the first nine to permanently leave the game. after Momonga's suggested guild name of "The H eteromorphic Zoo" is overturned they decided to go with the name  AINZ OOAL GOWN. NINES→AINZ OWN GOAL→OOAL GOWN.

to increase team work and give a common goal to focus on Momonga gave the first guild master order, conquering the recently discovered dungeon Nazarick.
