Remember this post where I talk about the points "for" and "against" who Nightbringer could be, with the obvious choices being Barbatos and Michael (seriously read that post, so that this post will make more sense)
Ok so more points! To be honest though, this post is less about Barbatos vs Michael and more about Demon vs Angel
1.) MC actually meets and talks with Nightbringer who says he's a demon
BUT he says it like this:
• Barbatos should know by now that MC has never had a problem trusting demons. They're literally in the situation they're in now because they gave a book that could have easily stopped him to the demon that was trying to kill them 5s ago and then pledged to protect that demon & his family and keep them happy
• Angels on the other hand do think like this. We see it from what Luke & (to a lesser extent) Raphael say. From what Lucifer says when he first meets Diavolo. From the (pretty fucked up but also lore/relationship building) angel event. Even from Simeon every once in a while.
2.) It's (probably) not present Barbatos because Nightbringer says that the new path that MC is on will bring about true happiness, whereas the path MC was already on (post s4) was already steadily moving towards what Diavolo wanted (they had a human employed in a high position in the Devildom hello???), and so was also what Barbatos wanted. I'd say it's also probably not past Barbatos (and I talk about why in the post I linked up top)
3.) Nightbringer, also tries to guide MC and get them to do what he wants because he thinks that's the best path, even when they repeatedly say they don't want this. This also feels like something an angel would do? Like demons make pacts with humans and then they have to listen and do whatever the human commands them to. Angels become guardian angels for certain humans, they're not supposed to interact with the humans but they are supposed to protect them - that sounds like there's a lot less of the human's decisions/choices/free will being taken into consideration than when in a pact with demons.
4.) Adam says he heard trumpets right before he met Nightbringer. And look it's been like over a decade since I read the Bible (so please correct me if I'm wrong) but aren't trumpets very famously associated with angels?
5.) Say we take Nightbringer's name very literally, as in Night - Bringer. And Nightbringer's little slam poetry sesh after talking with MC implies it should be taken literally. He brings darkness. And um....
Now I'm not placing all my bets on Nightbringer being an angel.
There's always the possibility it's a third secret Barbatos (which I think would be very funny) or a completely different character
Right now, I'm just simply laying out all the facts that we've been presented with. Eiher way I'm excited to find out who it is (and punch him in the face. I think MC deserves to break his jaw)
9.) Presumably-Michael says that the MC allying with Nightbringer would piss the Celestial Realm off
