Log Horizon (記録の地平線ログ・ホライズン Kiroku no Chiheisen, lit. "Recording the Horizon") is a small but immensely influential guild in that was formed in Akiba after the Catastrophe. Shiroe, its guild master, established it with Akatsuki, Naotsugu, and Nyanta to establish the Round Table Alliance, take down Hamelin, and restore order to Akiba..

The guild's name represents "the horizon of all we've documented."[1]


Log Horizon was founded by Shiroe, after years of declining guild invitations and offers, in order to do the "most incredible thing possible." To revitalize the city of Akiba, rein in the strength of the large guilds, and drive out the malicious and abusive guild Hamelin, Shiroe decided to establish the guild with the members of his party.

With its sister guild, the Crescent Moon Alliance, the newly-established Log Horizon began to enact its plan to make waves in Akiba. Using Marielle's popularity and Shiroe's reputation, the two garnered interest throughout the city through stunts like the Crescent Moon Refreshment Stand.

After establishing the Round Table Alliance and forcing Hamelin to disband, two of the guild's captives whom Shiroe had previously mentored, Touya and Minori, joined Log Horizon. They partied with Serara and Isuzu (members of the Crescent Moon Alliance), and the solo player Rundelhaus Code for the Summer Training Camp. They stuck together when the Return of the Goblin King scheduled event interrupted the training camp. During a fierce battle, Rundelhaus sacrifices himself to protect the party—and reveals that he is not an Adventurer at all, but a Person of the Earth. To save his life, Shiroe created a contract with Rundelhaus to join the guild and to give him the Adventurer subclass forcefully, allowing him to resurrect at the Cathedral. Since Isuzu was close to Rundelhaus, she decided to transfer to Log Horizon to stay with him. Although Nyanta invited Serara to come along, she turned down the offer due to her strong commitment to Crescent Moon Alliance.

Later on, Shiroe and Naotsugu go to Susukino to employ Silver Sword's aid in completing a raid. They were accompanied by Demiqas and Tetora, an Adventurer from Minami who was sent on Kazuhiko's orders. Following the mission, Tetora decides to join Log Horizon as its Cleric.


Though Log Horizon has a relatively small number of members, half of them are veteran and experienced players, with three from the infamous Debauchery Tea Party: Shiroe, Naotsugu, and Nyanta. While Akatsuki had doubts about her own strength, her guild mates and powerful players like Soujiro Seta and Rieze have recognized her competence. Tetora was recommended to Shiroe by Kazuhiko and was very helpful during the raid in the Abyssal Shaft. Their true strength is their ability to work together along with Shiroe's extraordinary organization and impeccable planning abilities. By studying their opponents and predicting their actions Shiroe can maneuver his guild into a position of strength before their enemy even acts.

The guild also has tremendous political influence as the guild that was instrumental in forming the Round Table Alliance and a standing member of the alliance.

While low leveled, Touya, Minori, Rudy, and Isuzu are considered strong for players of their level, little doubt because of their cohesiveness.


Spoiler warning!
This article contains plot details for Season 3 and beyond.

There will be a total of 12 members in Log Horizon—one for each class (in the Yamato server).[2] As of volume 13, eleven of the twelve classes have been accounted for.

The guild members are effectively divided into two parts; senior members and junior members. The senior members are not ranked by membership seniority, but rather by experience in Elder Tale and their levels; this is why Tetora, who joined much later than the members in Touya's Party, is considered a senior member.

Guild Base

Log Horizon Guild Base

Guild base map (as of volume 5)

After purchasing the guild house building allowing him to form the Round Table Council, and disbanding Hamelin, Shiroe decided to purchase a brick building in the outskirt of Akiba close to the north border of the city zone as their guild base. Half of the reasons is that he may be involved in a series of grand events and discussions in the near future, thereby needing a spacious, flexible building.

There are 6 floors and 1 basement level. According to the guild base map on the right-hand side, each area is allocated as the following:

  1. Bathroom
  2. Restroom
  3. Shiroe's room ("guild office")
  4. Nyanta's room
  5. Minori's room
  6. Touya's room
  7. Kitchen
  8. Dining room
  9. Wooden deck
  10. Naotsugu's room
  11. Akatsuki's room
  12. Isuzu's room
  13. Rundelhaus' room
  14. Laundry room
  15. Water tank

Isaac came to help Log Horizon clean the building by assigning summoners to conjure Undines and wash the first two floors (in anime, all floors are washed and the windows to the building destroyed). Marine Organization was hired to build stairs connecting between floors. The Roderick Firm was also hired to repair a water tank and install a running water system.

Chapter 84 of the web novel refers to Shiroe's room as the guild's office (執務室) but notes that this designation is somewhat of an exaggeration, since Log Horizon is a small guild. However, because of Shiroe's duties with the Round Table Alliance, people often consult him on business, and he uses the room to receive visitor and petitioners. He spends so much time in this room that the other Log Horizon members joke that he's a "shut-in" (引きこもり).[3]
