"Well, it's compelling the body parts to move and distort."

But by that logic, any number of the Sternritter would qualify for "The Compulsory." Nianzol Wiezol "compelled" things to bend away from him. Giselle can "compel" people with her blood. As Nodt "compelled" people to feel fear. Heck, Gremmy "compelled" reality to alter itself however he wanted, and Yhwach himself has the power of "Because I Said So, Nyah!" I'm still leaning towards wrong English rather than esoteric use of the word "compulsory."
