Great Britain is ablaze with news of a so-called "Lord of Crime," a criminal mastermind responsible for the downfall of several unruly nobles. In truth, the Lord of Crime is not an individual, but rather a group consisting of William James Moriarty and his two brothers, Louis and Albert. Together, they wish to destroy everything rotten about their current world and create a new, fair society for all. To accomplish their goal, they must commit criminal acts, which the great detective Sherlock Holmes and his partner, John H. Watson, cannot abide by. A dangerous cat and mouse game begins between the Lord of Crime and Sherlock, with each trying to outwit the other. Yet Sherlock, despite his skills, has no idea that his foe is right under his nose. Involved with both parties is a woman named Irene Adler, who is as beautiful as she is cunning. No stranger to scandal, Irene has embroiled herself in one that may be too big even for her, as the classified documents she stole could shake the very foundations of the British Empire. Can Irene be saved, or does a deadly future await her?

Second half of Youkoku no Moriarty.

In the late 19th century, the British Empire has become a global power. Due to the strict class stratification, the average citizen has little chance of successfully rising up to the top, where the despicable nobility rules over them all. William James Moriarty, the second son of the Moriarty household, is a young mathematics professor who has displayed great cunning and intellect since he was a child. Along with his brothers Albert and Louis, he lives the simple life of a noble. Outside of school, William is a well-known private consultant willing to solve the problems of anyone in need. However, his gentle demeanor belies his position as the head of a group prepared to wreak havoc in pursuit of its desire—a new world built from the ashes of the old. Yuukoku no Moriarty puts a new spin on Arthur Conan Doyle's original work by putting the spotlight on its main antagonist and exploring how he came to be the first and only "criminal consultant."
