Rundelhaus Code

Rundelhaus Code (often called Rudy for short) is a character from the anime Log Horizon.

He is a young, noble-looking human Sorcerer who specializes in offensive magic. He initially presents himself as an eccentric and boastful adventurer with a loud-mouthed, egotistical, and somewhat narcissistic personality, though he grows and forms bonds with others over time.

In reality, he is one of the People of the Land (a native NPC of the game world) who pretended to be an adventurer. During a critical event, he is mortally wounded, but Shiroe saves him by creating a groundbreaking contract/spell that grants him the "Adventurer" subclass—allowing resurrection and other player-like benefits. As a result, he officially joins the Log Horizon guild, serving as a bridge between adventurers and the People of the Land.

He's commonly described as handsome (blond hair, blue eyes, prince-like vibe) but his brash attitude often overshadows that initially.
