James Moriarty (Ruler)

A kind, articulate young man, he's a little self-conscious about the frightening glare he always seems to have, but he's really quite amicable. He loves mathematics, and is constantly calculating or tabulating something. Perhaps he will make waves in mathematics, or become a great teacher... Whatever path he chooses to take, his future is bright!

He stands at a crossroads. Does he abandon his pursuit of glory, or sink into evil?

Ah, but that decision was made long ago.

I shall be the very avatar of evil.

Height/Weight: 175cm, 68kg

Origin: The Sherlock Holmes Series, Scandinavian Mythology

Region: All of Europe

Alignment: Chaotic-Balanced(?)

Sub-Attribute: Human

Gender: Male

Need it even be said that he is truly evil at heart?

While he may initially come across as bright and cheerful, once you learn that he will grow up to be a scheming old man in his fifties, his demeanor changes to match. As the future Napoleon of crime, he has evil charisma to spare.

His First Ascension shows what he's like as a clever college friend, or perhaps a high school classmate who agrees to share his notes but never lets you hear the end of it. His Second and Third Ascensions are more of a conscious choice to perform what he believes he will, or perhaps should, be in the future. However, it is almost impossible to see through this performance, as he tends to reinforce these self-imposed beliefs so strongly that even he forgets he's actually just putting on an act.

That said, he is still well aware that he lacks the evil charisma of his fifty-something self, and can't help but wonder what the difference is.

Conspiracy Formation: EX

A skill that is similar to, and yet nothing like, Territory Creation. Enables Moriarty to weave plots just like a spider weaves a web. Originally A+, it went up to EX thanks to this young Moriarty's innate ability to weave conspiracies without any conscious effort whatsoever.

Panic Cut: C+

Somewhat similar to Disengage, this skill enables Moriarty to stand back and reassess a scheme no matter how chaotic things may be at a given moment. Prevents him from being affected by mentally destabilizing debuffs.

Mathematical Thinking: A

Enables Moriarty to use razor-sharp mental calculations to constantly determine the optimal action in a given combat scenario.

Huh? You want me to take part in the combat, too?

Slide Rule Weapon: B++

Moriarty's slide rule is no ordinary tool; it is capable of transforming into any sort of weapon imaginable.

Um, excuse me? How did this happen to my slide rule?

As we said, it is a tool capable of transforming into any sort of weapon imaginable.

Roll of the Dice: EX

Later in his life, Moriarty will be faced with a choice. Should he go down the path of evil, or devote himself solely to mathematics? Although he carefully calculated every other decision he made in all his life up till then, he decided to entrust this choice, and so his fate, to the dice. What would they decide?

A Mathematical Extraction of Evil.

"MMA" for short, which is not to be confused with the popular combat sport. This Noble Phantasm extracts and lays claim to any latent wickedness in all targets currently on the field. Barring some especially saintly figures or mechanical life-forms, there is no being in the world absent at least some manner of wickedness within, so by extracting it, those beings are essentially rendered powerless. The reason for this is simple: without any wickedness, they also lose the will to fight and kill, which tends to be an important thing to have in the middle of a fight. Thus, if a target should be robbed of theirs while fighting, they are left all but defenseless.

『The Dynamics of an Asteroid』

Incomplete Final Equation.

A still unfinished mathematical formula for destroying an entire planet. While it could be used to unleash immense destructive power, the young version of Moriarty has chosen to seal this Noble Phantasm away. Why? Quite simply, because the equations are not yet finished, which means this thesis (read: Noble Phantasm) is still far from complete. If you look closely when his professor self says to him, "Pardon my layman's ignorance, but I have a question," you can actually see his hair stand on edge.

The devilish boss of the criminal organization which practically controlled all of Europe from behind the scenes. An incredibly cautious man, nobody knows his true identity; even the people of his own organization remain ignorant.

However, this version of him is who he was before all that, a young Moriarty, still full of hope, and with a promising future ahead of him. Even so, his important life choices have already been made, and he knows he will continue on the path that will lead him to become a cruel, cold, calculating villain.

In his youth, Moriarty had his soft spots. He was even still a bit mentally fragile in some respects. In fact, his true personality at this point in his life is much more "friendly youth" than "scheming villain," a quality that is most clearly visible when he isn't wearing his makeup. Even the older Moriarty is proud of the man he used to be (and he certainly isn't shy about showing it, much as the young Moriarty wishes he would stop).

Although this Moriarty may claim that he sees Holmes as no more than an obstacle, it's clear that he actually spends a great deal of time thinking about his detective adversary. While he is still set on achieving his goal of becoming a charismatic villain in the future, he's also begun looking for different ways of being an evil boss thanks to the Master of Chaldea and his fifty-something self's influence.

In Traum

Even though he wasn't the Singularity's source, Moriarty was the one to appear as the final boss. In the time leading up to that, he met with Kriemhild, Kōnstantînos XI, and Pope Johanna, and encouraged them to continue waging a deadly war between their respective realms. Moriarty had multiple goals in this Singularity, one of which was to make a complex situation even more complex (particularly focusing on the kind of complexity Moriarty was personally quite fond of).

First, to arrange a stage on which to kill Sherlock Holmes once and for all.

Second, to sow further chaos throughout the Singularity and prevent the Foreign God from suspecting his true motives.

And finally, to leave Chaldea so desperate, they would turn to him as their savior.

This is why he first acquired the essences of the three Norse goddesses of fate: Urdr, Verdandi, and Skuld. Thanks to their ability to measure and spin threads of fate, he was able to nullify all attacks directed at him by declaring it was not his fate to be injured, and to remove all obstacles in his way by declaring it was his fate to overcome them. However, as Mash pointed out, even this power has a weakness: if used to overcome your fate in a dramatic fashion, it punishes you with significant and unavoidable debuffs. After all, defeating your archrival as the protagonist in your own tale inevitably means bringing your tale to an end, which in turn means you can no longer be the protagonist. This is why Holmes agreed to challenge Moriarty one-on-one; he hoped to more dramatically raise the story's stakes, as it were. Were it not for Holmes's loss, Chaldea might never have been able to defeat Moriarty.

In the end, Moriarty and his Spirit Origin vanished into the ether, but not before leaving behind one last unbelievable mystery.
