Description
James Moriarty initially appears cheerful and affable as the leader of the Kabukicho Irregulars, a band of delinquent youths stealing from the wealthy to aid the poor. This role earns him the informal title of "captain" among Kabukicho’s east-side youth, though early hints suggest a concealed darkness beneath his friendly exterior.
He is the son of Shinjuku’s ward mayor, originally from the affluent west side. His defining trauma stems from the murder of his twin sister, Alexandra Moran, by the serial killer Jack the Ripper. Believing himself indirectly responsible—as she died wearing his clothes during a solo trip to Kabukicho, potentially drawing the killer’s attention—he abandons privilege to infiltrate the district under an alias, consumed by vengeance.
His relationships prove complex. He forms an early friendship with Sherlock Holmes, admiring his rakugo performances and occasionally collaborating on cases. John Watson also trusts him initially, but Moriarty deems Watson a threat after the doctor discovers a transmitter in Alexandra’s corpse during an autopsy—evidence linking her death to broader conspiracies. Watson thus becomes both witness and obstacle to Moriarty’s revenge.
The Jack the Ripper case’s climax marks a turning point. After identifying the killer, Moriarty publicly slashes their throat despite pleas from Sherlock and others to avoid becoming a murderer, resulting in his arrest and imprisonment. Post-escape, he undergoes a drastic transformation: employing hypnosis to manipulate captured criminals into suicide, displaying utter detachment from human life. His methods escalate in ruthlessness, including gaslighting Watson into believing he is Jack the Ripper to further his goals.
His demise follows collaboration with Irene Adler to destroy evidence of government corruption. After success, he stages his death by drowning—a final act controlling his narrative while shielding allies from entanglement. His last message to Sherlock and Watson expresses gratitude for their brief friendship, acknowledging their role in his emotional journey.
A six-episode OVA explores his backstory further, though the available sources lack specifics from this installment.
