William James Moriarty

William is described as a handsome young man with scarlet, "expressive" eyes. He has pale skin and a slim build, with medium-length, light-colored, curly hair with long side bangs and an elongated side fringe. He is said to look better when he smiles.

He typically dresses in classic suits, appropriate to the Victorian era and his social standing. His appearance is neat and tidy. He often carries a cane, which is actually a disguised blade, and wears a top hat. During certain "missions," he also wears a black hooded cloak over his regular clothes, covering his face.
William is a true genius, demonstrating his extraordinary intellectual abilities from childhood. He possesses a charisma that draws people to him. He also feels compassion for others and has a heightened sense of justice.
The qualities he developed in childhood help him gather people who share his views as he grows up. He has an extremely negative view of the current social system, which encourages class inequality. In pursuit of his goals, he displays cruelty toward those at the top of this system and compassion for those at the very bottom.
William and his younger brother, Lewis, were orphans without a home, sleeping in a bookstore. Thanks to his intelligence, the boy helped people, receiving food or money in return. At the age of 10, he and his brother were sent to an orphanage, where they soon met Albert Moriarty, the eldest son of Duke Moriarty. Inspired by William's ideas, the young man decided to take him into his family so that he could bring them to life.

He is a mathematics professor, but behind the scenes he operates as a criminal mastermind nicknamed the "Master of Crime", making him Sherlock Holmes's archenemy.
