Alexis Leon Midford, Marquess of Midford, leads England's highest chivalric Order of the Garter. He shares his life with Francis Midford and is father to Edward and Elizabeth Midford, placing him as uncle by marriage to Ciel Phantomhive. His title connects to Mitford in Northumberland, signifying a "ford at the junction of two rivers."

A middle-aged man, Alexis possesses thick eyebrows, a mustache, a cleft chin, and slicked-back flaxen hair. His attire consistently reflects his noble standing through formal, sophisticated clothing.

Alexis openly expresses warmth and affection, a contrast to his wife's reserve. He embodies the knightly code, championing the protection of the vulnerable and unwavering leadership. This commitment manifested during the Campania crisis, where he prioritized passenger safety over his own, declaring that abandoning the helpless violated the knights' principles.

His past includes attending Weston College, serving as the prefect's fag for Green Lion dormitory alongside Vincent Phantomhive. He rose to become England's head knight. His marriage to Francis followed her victory over him in a fencing match organized by Queen Victoria. He participated in Ciel Phantomhive's ceremonial decoration as Earl in March 1889.

In April 1889, Alexis and his family invited Ciel aboard the luxury liner Campania. When Bizarre Dolls attacked, Alexis, Francis, and Edward declined evacuation, instead spearheading passenger defense and lifeboat operations. He reassured survivors by announcing himself as the Marquess of Midford and leader of the British knights. He secured his family's escape via lifeboat before the ship sank.

The name "Alexis," meaning "helper" or "defender," and "Leon," meaning "lion," align with his protective nature and leadership position.
