Thirty thousand Japanese gamers awake one day to discover that the fantasy world of Elder Tales, an MMORPG that was formerly their collective hobby, has become their cold hard reality. Severed from their everyday lives, they confront a new horizon filled with ravenous monsters, flavorless food, and the inability to die! Amid the chaos, veteran gamer Shiroe gathers his friends, the guardian Naotsugu and the assassin Akatsuki, and together they embark on an adventure to change the world as they know it!

Even though peace has seemingly been restored to Akiba, unrest churns beneath its surface. Learning that two of his students—the twins Tohya and Minori—have been bound to an unscrupulous guild, Shiroe makes his bid to bring order to the lawless streets. Are his band of handpicked veterans up to the task...?

A message has reached the Round Table, and in response, Shiroe and his comrades leave Akiba on a quest to establish exchange with the Continental Alliance. Meanwhile, the summer training camp where rookie players from every guild will hone their skills begins. Minori and Touya (along with others at their level) face failure after failure as they challenge the dungeons. Without Shiroe to rely on, their abilities will now be tested!

The stronghold of Akiba faces a new threat: a mighty goblin army! In their efforts to rebuild the city, the adventurers of Elder Tales had neglected important quests, and now they reap the consequences. With the revelation that in-game death leads to memory loss of the real world, the stakes have never been higher. And will cutthroat politics destroy tenuous new alliances before the real battle even begins?

In the sort of autumn afternoon that leaves maidens sighing, new enemies arrives in Akiba! And these enemies are more terrifying than any monster—they're human. Worse, their target is the very system at the heart of the city—the Round Table Council! Will the tenuous government that Shiroe's worked so hard to build survive this latest threat?

The unthinkable has happened—murder in the city of Akiba. The Libra Festival's events have left Akatsuki dispirited. Despairing and confused, she wanders the city in search of the murderer and a chance to gain the power and recognition she craves—but feelings alone will not be enough. A new chapter in the Log Horizon epic begins!

Shiroe left Akiba in search of 8,000,000,000,000 gold coins, setting off for the vast north lands. But, what he found there was a warning of a large scale raid about to occur. In Akiba's unstable situation, Shiroe's chosen raid members include the galactic idol Tetora, the leader of Silver Sword who refused to take part in the round table council, Massachusetts, and the man he defeated in Susukino who still hates him, Demiquas. ...Is everything really going to be alright?

To obtain their very own Magic Bags, Touya, Minori, Serara, Isuzu, and Rundelhaus set off on their very first journey as a five-member party! Their quest to find the materials soon becomes a cross-country musical tour, as Isuzu further explores what music means both to her and to the People of the Earth. But no ordinary gig awaits them, because the kids are on their first real adventure without aid. Will they really be safe in this world that's more dangerous than it seems?

When the Catastrophe hit, American Elder Tales player Leonardo was one of the many people trapped. Stuck on the Chinese server with none of his friends and surrounded by thousands of monsters, his situation is hopeless...until a headstrong girl comes to his rescue! Kanami, the former Debauchery Tea Party leader, recruits him for her party. Along with the hero Elias, the blank-faced healer Coppélia, and a strange white horse that can talk, the group resolves to travel to the Japanese server, the only place where the new expansion pack unlocked before the Catastrophe struck. The long trek eastward begins!

Nearly a year has passed since the Catastrophe, and it seems like no one is any closer to figuring out what exactly happened. But when Minori brings a letter from Roe2, the explosive contents rock Shiroe to his core! These revelations arrive just as an impending war threatens to consume Yamato, forcing every adventurer to decide whether to search for a way home or to throw themselves headfirst into a bloody battle alongside the People of the Earth. Whatever their choise, those hiding in the shadows won't wait before making their moves!
