This character actually does appear again waaayyy further into the story but I don't think he has any speaking lines then so this will probably be a one-off character too. There will also be more devil roles coming so stay tuned after this one's gone. As for a character, idk he's the bad guy of the chapter, no much to it.

Voice wise, just bring out your inner Black Ops Zombies voice (if you somehow dont know just search it up on YouTube, you'll probably find it pretty quick)
