Trivia

Heart-Shaped Graph
- He shares the exact ATK values at maximum with Voyager
- The equation x^2+(y-√(|x|))^2=1 that appears in his Noble Phantasm forms a heart-shaped graph.
- The crown featured in his 3rd and 4th Ascension artworks is based (though not an exact match) on the St. Edward's crown, the centerpiece of the British crown jewels, which were Moriarty's target in the influential 1939 film The Adventures of Sherlock Holmes.
