I don't think there is much I can't do since I pick my muses based on expanding my range anyway, BUT SURE WHY NOT

and my account name meanings:

blue_darkslayer - Dark Slayer is his unique Style from DMC3, however Dante uses it in DMC4. Thus, he is the blue Dark Slayer user

(Vergil's, that is.)

totallynottalon - My utter rejection of Sasuke's Devil Kings name of Talon. IT'S NOT TALON, AND I WILL CUT ANYONE WHO SAYS OTHERWISE

Train was thebadluckcat, because he was the assassin Black Cat, Chronos Number XIII, who delivered "bad luck" to his targets

IE gunned them down

Justin is straightforward with guillotineofgod. His Weapon form is a guillotine and he worships the Shinigami

and Black Star's "thisismyera" is an anime quote. He mentions his era several times early on, though that kind of drops off after a while
