Yuukoku no Moriarty

In the late 19th century, Britain controls a significant portion of the globe, with the wealthy living in opulence while the working class toils in hardship. Albert James Moriarty, from an aristocratic family, adopts two orphaned boys from a lower social class. The mistreatment the boys endure at the hands of Albert’s family fuels Albert’s disdain for the nobility. He enlists the help of the older boy, who possesses exceptional intelligence and a ruthless nature, to eliminate injustice. Their mission begins with targeting Albert’s own family.
