The former Prime Minister of a major power in his original world. He was suddenly transported to a different world one day, where he became an adventurer and began enjoying life in this new world, calling it a "vacation." He holds His Majesty in absolute regard and is extremely protective of Guest, who was transported along with him. His primary weapon is a gun that no one else uses due to its massive recoil. Other adventurers call him "Noble-san" because of his aristocratic demeanor, and no one ever mistakes him for an adventurer at first sight. No one knows he is a world-traveler except for Jill and Eleven. He generally speaks politely. First person: I (polite, formal - before transport), I (casual - after transport) Second person: You (polite)
