James Moriarty

He appears as a refined middle-aged gentleman with slicked-back grey hair and a well-groomed goatee. He wears a monocle and a sophisticated Victorian tailcoat adorned with intricate glowing butterfly motifs. His most striking feature is a massive, multi-functional black coffin that serves as both a heavy firearm and a tactical weapon.

Charismatic, calculating, manipulative, gentlemanly, eccentric, and protective.

Servant of the Archer Class and Leader of the Phantom Demon Alliance.

Known as the 'Napoleon of Crime' and the greatest rival of Sherlock Holmes, Moriarty was summoned as the Archer of Shinjuku by merging his essence with the Phantom of the Freeshooter. Although he initially plotted the destruction of the world to best Holmes, he eventually developed a paternal bond with the protagonist. He now serves Chaldea as a brilliant, if morally flexible, advisor and guardian figure.
