In the year 2126, a gaming highlight was released - the game "Yggdrasil," which offered MMORPG fans entirely new possibilities for in-game interaction between players. Enthusiastically, players stormed into the new fantasy world, and powerful warriors and mages formed guilds and communities to shape the fate of their server-based online world. Twelve years later, all of this is old news! Yggdrasil has hardly any players left, and the servers are set to be shut down, prompting some players from one of the most powerful guilds, consisting of 41 members, to call for an online guild meeting to spend the last moments of their Yggdrasil life together. However, only a sad four members show up to witness the swan song, one of them being the guild leader with the alias "Momonga." Gradually, everyone except Momonga logs out.
