After a brutal war, magic swordsman Kyle defeats the Demon King but is left dying. A crimson crystal sends him four years into the past to his once-destroyed hometown where he finds his lost loved ones alive. Armed with future knowledge, Kyle vows to prevent the coming tragedy and rewrite fate.

One day, while playing the online game Elder Tales, 30,000 players suddenly find themselves trapped in another world. There, eight-year veteran gamer Shiroe also gets left behind. The trapped players are still alive, but they remain in combat with the monsters. The players don't understand what has happened to them, and they flee to Akiba, the largest city in Tokyo, where they are thrown into chaos. Once proud of his loner lifestyle, Shiroe forms a guild called Log Horizon with his old friend Naotsugu, female assassin Akatsuki and others.

Hakuoro has lost his memory after succumbing to serious injuries. But thanks to an elderly woman and her granddaughter Eruruu, he is nursed back to health. His face is covered by a strange irremovable mask and he occasionally sees beastly visions. Eruruu now cares for him as he becomes accustomed to the village and its inhabitants, who all bear strange ears (the women also have tails). Though these people venerate the forces of nature, desecration of an altar forces them to take drastic measures to preserve their lives from the wrath of Mutikapa-sama, guardian of the forest.

Witches were once respected for the wisdom and magic they gifted to humans. But with the rise of the Gear Expansion era, the new science community deemed them as enemies who hindered the progress of society. Thus began the slaughter of all witches, including one who had mentored a human boy named Adonis. After witnessing her death, Adonis vows to bring bloodshed and terror to the human race.
