«Ymir» (ユーミル, Yūmiru?) is the company that acquired ALfheim Online after the game was suspended, due to the inhumane experiments carried out by a small team from RECT Progress Inc., led by Sugou Nobuyuki.


After Sugou's inhumane experiments on 300 captured SAO survivors in the administrator-locked area atop the World Tree in ALfheim Online were made publicly known, RECT and the whole VRMMO industry suffered a huge blow. RECT Progress was disbanded due to said experiments and even the main RECT office suffered heavy losses, while ALO had to be suspended.[1]

At this time, former ALO players who had many people from venture companies, funded a new company, Ymir, which bought all ALO data, from RECT for a very small fee and re-established the world of ALfheim, improving it with several major changes.[1] Due to the bought ALO data including copied data from the old Sword Art Online server, New Aincrad (with several changes from the original Aincrad in SAO)[1] and Sword Skills[2] were introduced into ALfheim Online and surviving SAO players were able to inherit their avatar data from SAO.[1] The company also established Yggdrasil City in the place of the alleged Floating City[1] and introduced a new type of Sword Skills, Original Sword Skills.[2] All former ALO players were able to inherit their avatar data from the old ALO and only less than ten percent of the players left due to the RECT incident.[1]
