The Apocalypse has locked thirty thousand players inside the game, and no one knows what to do. The larger guilds are taking over Akihabara, and outside the city violent groups are Party Killing other players. A young female member of Marielle's "Crescent Moon Alliance" is trapped in Susukino, far to the north, and needs their help. Shiroe feels somewhat embarrassed, but makes a decision.

Serara, a young female member of the guild "Crescent Moon Alliance", is trapped by mysterious men in the northern city of Susukino and needs help. Shiroe and his friends travel to reach her. Annoyed by the game's tasteless food, they travel northwards, and go inside "the depths of Palm", a crumbling series of old mining tunnels. There they meet creepy monsters...

Shiroe, Naotsugu, and Akatsuki reach the northern city of Susukino, and safely meet Serara. With the help of the mysterious swashbuckler Nyanta, they plot to leave Susukino. But the evil guild Brigantia wants to stop them. The high-level monk Demikas attacks them. Can they overcome the odds?

Shiroe and his group take Serara southwards. On the way, they stop at the house of one of the "People of the Land". The people of the land were originally only characters in the game, with no personalities or unique traits of their own, but as Naotsugu talks to them, something seems odd... The party gradually realizes that the world isn't the same as it was when it was a game.

Shiroe returns to Akihaba and Marielle tells him what the town is like. The initial chaos has subsided, but the larger guilds are in control, and evil guilds are tricking new players and taking advantage of them. Shiroe is angred by this, and tells Naotsugu, Akatsuki, and Nyanta of his plan. And then he tells the Crescent Moon Alliance that he's going to clean up the city of Akihabara.

Nyanta told Shiroe the secret of making real food in this world. With Marielle's help, the Crescent Moon Alliance begins a fast food stand, and their "Crescent Burger" is hugely popular with players who are sick of tasteless food. BUt Shiroe's real goal isn't to sell hamburgers, and with Henrietta he begins to work on the next phase of his plan.

After the success of their Crescent Burger, Marielle and Henrietta meet with the members of the major crafting guilds of Elder Tale: Karashin of Shopping Street 8, Michikata of the Marine Agency ,and Roderic of the Roderic Merchant Association. They use Shiroe's plan to dangle the secret recipe of the Crescent Burger in front of them, and the talented account Henrietta opens negotiations. What she wants is...

To make the city of Akihabara safe, Shiroe calls all the major guild masters to the guild building. His goal is to create a Round Table Conference, which will rule the city. But everyone there wants something different, and his plan is about to go bad. What amazing trick does Shiroe have? Meanwhile, behind the scenes of the conference, the plan to free the younger players from the evil guild Hamelin continues. The strategist SHiroe's quiet battle in Akihabara continues!

Shiroe confronts the 10 guild masters who represent Akihabara with the need to revitalize the town and bring peace and order. His calm and forceful manner brings them over, and the government of Akihabara, the "Round Table", is founded. After this work is done, his guild, "Log Horizon", joyously moves to their new location. That night, Nyanta fixes them his special curry.
