The second season of Log Horizon. 
 
After struggling to survive in a surreal existence they were suddenly thrown into, Shiroe and his friends have managed to restore order to Akihabara by defending the people against the Goblins in the Zantleaf Region. After six long months with the team gaining the trust of the many guilds that use the city as their home base, they must now prepare for their unforeseen future – and a tough winter ahead. Once shy and a little standoffish, Shiroe has stepped up and shown that he can be a great leader. But can he keep Akatsuki, Naotsugu, and the rest of the gang together as they start to have differing opinions on their future course of action? And will the clique agree to leave the safety of the holy land of Akihabara to head off to one of the other four cities and explore foreign lands of Elder Tale? Whatever they may decide, this world that was once a game for the players is now reality and they must decide what is best for each and every one of the members of the team.
