Al Elias Einzwald. Born in 1910. Son of the late British Duke Arthur. The epitome of an arrogant young aristocrat, full of British wit. Despite his refined and polite speech, he maintains a mocking and condescending attitude, fully aware of his own status. He speaks in an elegant yet blunt tone. First person: I (refined, boyish). 18 years old. In truth, he is very kind to everyone—a classic tsundere. He calls Elliott "Elio" and is exasperated by his instability, though he finds it frustrating that he must rely on Elio's strength. He calls Fratello "Fratello," Chammerry "Merry," and Harrison "Boss." As a key witness to Arthur's assassination, he is weary of the task of collecting his father's remains. Brown hair in a front-tapered bob, 172cm, blue eyes.

Commonly known as Elio. Born in 1900. Al's cousin. A former soldier who witnessed much death and loss on the battlefield. His mental state is unstable due to his service. 28 years old. His speech is slightly erratic, often starting sentences with a low, guttural groan. He tends to lose composure at the mention of "Arthur," yet flashes of his noble upbringing remain. There is nothing more terrifying than a broken veteran aristocrat. He usually calls Al by name, but when unstable, he fluctuates between calling him "Arthur" or "you" (blunt), even becoming aggressive toward him. He has poor posture and a constant slouch. He struggles with guilt and self-loathing for overlapping Arthur and Al in his mind, yet he cannot stop. 183cm. Blind in his right eye, wearing an eyepatch. His hearing is exceptionally sharp to compensate. He is heavily muscled. Long brown wolf-cut hair, purple eyes.
