30.000 jugadores japoneses, han sido transportados al interior del famoso MMORPG “Elder Tale”. Sin posibilidades de desconectarse y en un mundo completamente nuevo, comienza a generarse caos e incertidumbre por todas partes. Uno de estos jugadores es Shiroe, que junto a su viejo amigo Naotsugu y la asesina Akatsuki, intentaran descubrir por qué quedaron encerrados en el interior del juego, mientras exploran y aprenden a sobrevivir en este nuevo mundo.

Las cosas van de mal en peor en Akihabara. Los grandes gremios se están haciendo con el control de la ciudad, asfixiando con ello a los gremios más pequeños y en el exterior las cosas son aún peores. Grupos de PK (Player Killer) están acabando con los aventureros que se atreven a salir de la cuidad. Mientras, un miembro del gremio “Crescent Moon Alliance”, está atrapado en la ciudad de Susukino, 500 km al norte.

Shiroe, Naotsugu y Akatsuki se dirigen al norte, a la ciudad de Susukino, para rescatar a Serara, una integrante del gremio “Crescent Moon Alliance”. Sin embargo, para llegar a la ciudad, primero deben adentrase en el “Abismo de Palm”, una peligrosa red laberíntica de mazmorras y minas.

El grupo al fin consigue llegar a Susukino, sin embargo, es una ciudad sin ley, dominada por Demikas y su gremio, Brigandia. Por suerte, el grupo se encuentra con Nyanta, un gato duelista, que parece conocer a Shiroe y que está dispuesto a ayudar a sacar ilesa a Serara de la ratonera en la que se ha convertido Susukino.

El grupo comienza el camino de regreso a Akiba y Shiroe no puede dejar de pensar en un par de jugadores novatos que conoció antes de quedar encerrado en el juego. Además, descubre que los PNJ están más vivos de lo que parece y que Elder Tale es ahora, algo más que un juego.

De regreso en Akiba, Shiroe se da cuenta de que la ciudad está en un estado deplorable. Además, el mal presentimiento que tenía durante el viaje de regreso se ha cumplido. Un gremio llamado Hamelin está reclutando jugadores novatos, para traficar con sus Exp Pots (Pociones de experiencia).

Recap of the first six episodes of Season 1.

Shiroe está decidido a hacer limpieza en Akiba y rescatar a los jugadores novatos de Hamelin. Para ello, decide utilizar lo que le enseñó Nyanta, como darle sabor a las comidas de Elder Tale. Aunque este no es más que el principio de su plan.

Crescent Moon ha llamado la atención de todos con su puesto de comida y es el momento de avanzar en el plan. Para ello, Marielle y Henrietta deben conseguir los fondos necesarios de los tres gremios mercantiles más importantes de Akiba, en una batalla de ingenio y negociación.

Shiroe reúne a los líderes de los gremios más poderosos de Akiba, con la intención de crear una conferencia de la Mesa Redonda. Su idea es hacer que los gremios presentes en la mesa, rijan las leyes y normas de la ciudad de Akiba. Sin embargo, cada uno de ellos tiene sus propias ideas y la creación de la Mesa Redonda parece inviable. Mientras, comienza la operación para rescatar a los jugadores novatos de Hamelin.

Shiroe expone las leyes y reglas que pretende instaurar en la ciudad, para mantener el orden y la paz. Finalmente consigue el consenso y llega la hora de celebrar que Akiba por fin tiene un gobierno, la Mesa Redonda.

La Liga de las Ciudades Libres de Eastal, envía una invitación formal para asistir a un baile a los representantes de la Mesa Redonda. Shiroe decide asistir para intentar recabar información sobre la Gente de la Tierra. Por otro lado, la Mesa Redonda decide realizar un campamento de entrenamiento en la playa, para los novatos de nivel inferior a 40, en el que participan Minori y Touya.

En palacio continua el baile con recelo de los nobles hacia los aventureros. Mientras, Minori está preocupada por su inminente entrada en la mazmorra del bosque de Lagranda. El grupo designado para adentrarse en las profundidades son Minori, Touya, Serara, Isuzu la bardo y Rundel Haus el hechicero.

La Gente de la Tierra comienza a abrirse a los aventureros, aunque con algunos recelos. Crusty ve en la princesa Rayneshia una oportunidad y comienza a acercarse a ella. Por otro lado, el grupo de Minori y Touya tienen graves problemas para enfrentar a los no muertos de la mazmorra del bosque de Lagranda.

Shiroe y Akatsuki son llevados a la biblioteca del mago Regan. Una vez en ella, Regan les contará multitud de cosas sobre la historia de Elder Tale, la magia y un escalofriante secreto que afecta directamente a los aventureros.

Shiroe está preocupado por las revelaciones de Regan sobre Elder Tale, por lo que decide mantenerlas en secreto. Mientras, Minori encuentra el valor suficiente para hablar con el grupo sobre los motivos por los que siempre son derrotados. Minori consigue que todos se abran y cuenten en detalle sus habilidades, fortalezas y debilidades.

Un ejército de 10.000 goblins se dirige hacia la ciudad de Mahiama. Mientras, un pequeño contingente de goblins se dirige al pueblo de Choushi, donde realizaban el campamento de entrenamiento los jóvenes novatos de Akiba.

El ataque a Choushi a comenzado y ante la negativa de Marielle y los adultos de defenderlos, Minara, Touya, Serara, Isuzu y Rundel Haus, deciden proteger el pueblo. Mientras, los nobles desconfían de los aventureros, lo que provoca tensiones que amenazan con una ruptura entre las dos partes.

La princesa Rayneshia se dirige hacia Akiba con la intención de pedir ayuda a los aventureros contra los goblins. La llegada de Rayneshia es todo un acontecimiento en la ciudad, pero aún le queda lo más difícil, convencer a los aventureros para que ayuden a la Liga de Ciudades Libres de Eastal.

Rayneshia ha conseguido el apoyo de los aventureros para hacer frente a los goblins. Mientras, Minori y el resto, luchan valientemente en Choushi contra la cada vez mayor amenaza de los goblins. Crusty lidera la ofensiva de Akiba, que demuestra una fuerza inconmensurable.

Rundelhaus ha sido herido de muerte y ningún hechizo parece devolverle a la vida. Es entonces cuando Isuzu revela un terrible secreto. Rundelhaus es una persona de la tierra, no un aventurero, por lo que la magia de resurrección no servirá con él. Minori, decide contactar con Shiroe, con la esperanza de que pueda hacer algo por su amigo. Mientras, la batalla contra los goblins llega a su punto álgido.

Se celebra un baile en el Palacio de Hielo Eterno, para celebrar la victoria sobre los goblins. Mientras, Shiroe escucha una intrigante historia de boca de Regan. Un baile protagonizado por Crusty y Rayneisha da por concluida la disputa entre la nobleza y los aventureros.

Se ha dado luz verde a la celebración del primer festival de Akiba desde el Apocalipsis, el Festival Libra. Toda la ciudad está ayudando en la preparación y se respiran aires de fiesta. Sin embargo, Shiroe permanece encerrado con el papeleo y los estudios, por lo que Minori y Akatsuki tienen la misma idea, tener una cita con Shiroe.

Comienza el segundo día del Festival Libra. Todo parece ir bien, hasta que comienzan a aparecer disturbios y quejas por toda la ciudad y todos siempre son protagonizados por Gente de la Tierra.

La Gente de la Tierra protagoniza peleas, rumores, accidentes y toda clase de altercados que ponen en jaque a la seguridad de Akiba y al mismísimo Shiroe, que se siente abrumado. Mientras, la llegada de un importante noble procedente de la ciudad de Minami, no hace más que agravar la situación.

Por fin se descubre a la persona detrás de los altercados en Akiba y se consigue neutralizar su manipulación. Cuando todo el mundo festeja el final del Festival Libra, Shiroe se encuentra con una visita inesperada.

It's been six months since Shiroe and the other adventurers have been trapped in "Elder Tale". As Akihabara moves into late fall, the city is excited for the cultural fair. But Shiroe is ignoring the fun and speaking in secret to a land person, Kinjou, who controls the world's currency flows. When negotiations are over he tells his friend's leaving the city. The long-awaited second series of "Log Horizon" begins a new adventure!

They're looking for high-level adventurer's to help them get the the "Sacrifice Clan's Gold". Shiroe visits an unexpected person. Meanwhile, Naotsugu and Regan walk through the frozen town and find a small but pretty girl named Tetra. She calls herself a "galactic idol", and she's very irritating, but her level is 92...!?

Shiroe and his friends have come to the Depths of Palm to reach the Sacrifice Clan's gold. The underground labyrinth is filled with powerful monsters that wear them down in a war of attrition. Meanwhile, Akihabara, Akatsuki hears about the "Teachings". She's very interested to know that by completing a high level raid, she can greatly improve the level of her techniques.

It's almost Christmas in Akihabara. At Lenessia's mansion, Marie and Henriette are all visiting. Lenessia is smiling, but she can't open herself up to the adventurers because of how different they are. Akatsuki, who has been tasked with guarding the princess, is the only one who isn't having fun. She thinks of Shiroe and worries about her own powerlessness. Then, in Akihabara in December, a shocking event occurs.

A man appears in Akihabara and begins killing adventurers with powerful Royal Guard equipment. Lenessia is shocked to learn that he is one of the Land people, of the Kunie clan. Akatsuki goes to put a stop to him herself, as the West Wind Brigade scouts find him...

Akatsuki revives at the Cathedral and asks the others for help to defeated the murderer. She trains with the top members of D.D.D. and the West Wind Brigade in an attempt to learn the Teachings.

A full raid of 24 party members has been formed to defeat Nerelith! The maidens gather to defend Akihabara! Meanwhile, Lenessia and Henrietta head beneath the Guild Building for a certain mission...

On Christmas Eve, Shiroe and the other members are fighting the level 97 boss monster "Luseat of the Seventh Garden." But two more boss monsters appear in the middle of the battle, and they are overwhelmed. Shiroe is caught in the fires of "Ibrahabra of the Third Garden"...

William, the leader of the combat guild Silver Sword, faces a great crisis as his guild has been defeated and is thinking of going home and quitting. He gives an inspiring speech to rally them into the fight once more.

With honesty and renewed sense of comradery the team has a small chance of winning an unbeatable raid.

The final boss, Uru of the Ninth Garden vs the villain in glasses, Shiroe is up against what could be the strongest boss in this new world.

It's February 14th! Akihabara is filled with excitement as the adventurers enjoy their first Valentine's Day. Marielle and Isuzu try to make cookies out of Kokonia fruits, which are said to make someone fall in love with you. Meanwhile, in the Log Horizon guild house, Tetra puts Akatsuki and Minori up to cooking something for Shiroe.

When Elder Tale was a game, there were talented solo players who would come together whenever they felt like it and defeat difficult raids. Their name was "The Debauchery Tea Party." Now, their leader, the cheerful girl Kanami, is traveling through the vast lands of the Chinese server on her way towards Yamato.

As spring comes to Akihabara, Shiroe decides to send Minori, Touya, Isuzu, Rundelhaus, and Serara on a quest to get the magic bag, a convenient and critical item for high-level adventurers. The 5 excitedly put together their things and get ready to go on a journey.

The gang sets out towards the redstone mountains to get their magic bags. On the way, they meet a party of merchants who are being attacked by monsters. They save the merchants but are overwhelmed, when a girl who looks just like Shiroe saves them.

Continuing on their way to the Redstone mountains, the gang encounters a mysterious group: the Odyssey knights, a group of players who'll do anything to get back home. Their eyes are strangely lifeless, and they're carrying a strange altar that allows its users to ressurect immediately.

Dareila joins the party at the Boxurt mountains, and the group stops at the town of Saphir. Isuzu learns that the reason the land people enjoy her songs so much is because the world only has 42 songs in total. She gets very sad and stays in her room, but then a giant flock of wyverns descend upon the town.

A massive flock of wyverns suddenly attacks the town of Saphir! The party tries their best to protect the town, but the Odyssey knights are constantly flinging themselves to their deaths. Meanwhile, Roe-2 looks at the brutal combat and doesn't even blink an eye...

A Minami plot was behind the massive wyvern attack on Saphir. To stop the plot, Nyanta attacks the train carrying the Minami general alone. But he's faced with the sorcerer he defeated long ago, the man who trapped Serara in the far north, Londark.

At a party for the crown prince's birthday, assassin's make an attempt on his life.

They're here! They're here! A whole swarm of moths!

Only fifteen minutes and thirty seconds until moonrise!

Princess Rayneshia has resided in Akiba for a while now, getting along with the people in town. One day, she receives a visit from her mother Sarariya and is told that she will be engaged soon to the head of a powerful noble family.

Touri of the Saiguu Family, Princess Rayneshia's husband-to-be, sends a messenger to let her know the preparations are in place for their marriage. Meanwhile, Eins declares that Honesty will secede from the Round Table Conference.

When Shiroe goes to see Eins to discuss the future of Akiba, he finds the head of the Saiguu Family was also waiting for him. They ask Shiroe to help them with the Akiba Government. The answer Shiroe reaches is…

The residents of Akiba are notified of the election. Both parties campaign to gain their support. Meanwhile, Rayneshia needs to face her mother to get permission in order to be part of the New Round Table Conference.

Election day has finally come. Standing in front of Adventurers and the People of the Land, both Eins and Rayneshia give sincere speeches. Votes are cast and starting to be counted. What will the result be?

Krusty has something to tell Shiroe. In his message, he recounts what happened to him after he disappeared, as well as his encounters with Enchantress Youren and the Ancient hero Elias Hackblade.

Krusty and Kanami's group face their enemies in Sirius Grotto. During the battle, the truth about Enchantress Youren comes to light. Will Krusty be able to overcome his curse?

At the Round Table Conference gathering, people notice that Rayneshia seems to be preoccupied by something. Meanwhile, on their way back from training, Toya and the others find Ancient sisters.

Minori finally gets to go shopping alone with Shiroe. While exploring the store, she learns a lot about items and raids. Meanwhile, Shiroe checks in with Isaac to see if he's noticed anything unusual.

One morning, the Adventurers wake up and realize that the Akiba they're currently in isn't the Akiba they know. With reduced levels, they start to feel helpless, but Shiroe notices there's still hope.

The young Adventurers challenge the raid. Without any adults' help, they must defeat the enemies and bring back normality to Akiba. Can they beat this raid by themselves?

The young Adventurers fell to despair by Ereinus. However, Akatsuki, Lelia, and Litka's fighting spirit reinvigorates the team’s morale. Under Minori's command, they stand against the Genius once again.
