I doubt it because I personally believe the bolded have been written out of the series for one or more games and, traditionally, a game where protagonists undertook the Mark of Mastery had them all be playable.MOM could also potentially be Mark of Mastery? There’s a number of characters who could potentially be ready to take the test. Terra, Ventus, Kairi, Lea, Roxas, Xion, and Sora are all wielders who aren’t masters. If it truly is DDD vol 2, character(s) taking the Mark of Mastery could work well.
