Rundelhous Code ("Rundel Haus Code" in the Crunchyroll translation of the anime), also known as Rudy, is one of the People of the Land in Elder Tale. He is a Human Sorcerer-Adventurer and currently a member of Log Horizon. He was a member of the Shibuya Raid Team.

His birthday is November 11[3].


Rundelhous is a young, noble-looking boy with blond hair and blue eyes. He has been described as attractive by a few characters, although his popularity is decreased by his somewhat eccentric personality.


Rundelhous is a brash and boastful person, and slightly narcissistic. He has a habit of using English terms when being especially flamboyant. Despite this, he is rather hardworking and heroic in certain situations, more than willing to give up his life to protect Choushi Town (a drastically more significant sacrifice, because as a Person of the Land, he dies permanently).

He's shown to be quite naive in certain situations, such as not realizing that his role as a Sorcerer does not put him on the front lines, and that his current level (at the time) was basically the same as Minori's.  

While introduced at level 23, his level is at or above level 25 as he wears the Magical Gauntlets. These gauntlets were the first item that Tohya's Party acquired together. Most recently, in the Route 43 arc, he is shown to have reached level 58.

Out of all of the Log Horizon members, while he loves them all, he seems to get along with Isuzu the best, with Tohya a close second.


Prior to the CatastropheEdit

The third son of a corrupted noble family of Ninetails Dominion[4], Rundelhous Code, nicknamed Rudy, was one of the Landers that inhabited the world of Elder Tale. As he grew up, he was captivated by the freedom and sense of justice of Adventurers who fought for his people. After the Catastrophe, this admiration subsequently led to him taking on the guise of an Adventurer. He put tremendous effort into this guise; as a Lander, his EXP leveling rate was 1/4 that of an Adventurer, yet he was able to achieve a class level similar to beginning adventurers before his status change (most professional POTL soldiers only have a level in the low teens at best).

At some point, his hometown was destroyed.[5]

Round Table Alliance arcEdit

Rundelhous makes several cameos, watching the starry sky and purchasing a Crescent Burger.

Summer Training ArcEdit

Pretending to be a Sorcerer, Rudy joins a summer training camp in the Sand Leaf Peninsula hosted by the Round Table Alliance for the low-level adventurers of Akihabara. He is grouped with twins Minori and Tohya and Crescent Moon Alliance members Isuzu and Serara to challenge the Ragranda Forest dungeon.[6]

Though initially having a difficult time working as a team, the five learn to work together after learning about each others' skills and abilities. Their teamwork allows the team to successfully clear their half of the dungeon, even defeating a powerful monster called Burning Dead.

As the days go by, Rudy grows close to the Bard Isuzu. While camping outside one night, Isuzu discovers of Rudy true identity as a Person of the Land when she is unable to add him to her friend list. Isuzu promises to keep it a secret after learning of his strong desire to live as an adventurer.

Return of the Goblin King ArcEdit

As the team grows stronger by the day, the event Return of the Goblin King triggers. Goblins, as well as Sahuagins, invade the Sand Leaf Peninsula. The invasion endangers the town of Choushi and the adventurers training in the peninsula decides to guard it.

While the other members of the training camp defend Choshi town from the Sahuagins invading from the sea, Rudy and his party mates successfully eliminating several goblin parties all by themselves, proving to be excellent assets for the defense. However, fatigue and the number of the enemies overwhelm the group as they fight a party of goblins, hobgoblins and dire wolves. Faced with the possibility of them being wiped out and the town being overrun, Rudy sacrifices himself to defeat the enemy.

As Rudy dies, Serara and Minori try to resurrect him to no avail. Desperately, Minori calls her guild master Shiroe for help. Shiroe arrives minutes later and manages to save Rudy by having him sign a top-class contract that he created. In exchange for being a member of Log Horizon, the contract forcibly gives Rudy the Adventurer subclass, giving him all of their abilities, one of which is the ability to respawn at the Cathedral when he falls in battle which saved him from death.

Libra Festival arcEdit

Route 43 arcEdit

Rudy joins to the rest of Tohya's Party on their quest to acquire Dazaneg's Magic Bag. At Lander villages, the scrubs (sans Rudy) would perform for them, and Isuzu starts gaining a fandom among them. She dismisses her music as just stuff to do in her spare time, but then Rudy reveals why the Landers loved it so much: they themselves could only play 42 tunes. Because of that, they find Adventurers amazing. This fact makes Isuzu upset, because she feels like she’s cheating the Landers by playing music that wasn’t hers. However, Rudy reassures her that it’s okay because it makes people happy, and that’s what matters.

During the Wyverns' invasion in the city of Saphir Rudy determines to save this town, wanting to spare it from the fate of his own hometown. In the middle of the battle Isuzu becomes more desperate. Throwing away her spear, she takes out her lute, to Rudy’s surprise.

She sings a song that she created herself, the 43rd Song, which filled the air with rainbow-colored notes and turned the rubble into shields, protecting the Landers and the Adventurers.

After the battle, the kids decide to leave the day after. Rudy understood that some Landers would blame the Adventurers for what happened and for not protecting everyone, and didn’t want his friends to be hurt by those words. As they are leaving, Rudy and Isuzu hear some Lander children singing. It’s Isuzu’s song, which has reached their hearts and has truly become the 43rd song. As she burst into tears, Rudy hands her his handkerchief. It’s her birthday song, a song that will spread throughout Yamato. 

Homesteading the Noosphere arcEdit
