The Angels

Do you guys think the angels are the final bosses or the raiders I could potentially see the raiders allying themselves with the cleaners if the angels get in their way or sum. Because the angels seem more like the over arching villains of the story as they are the mysterious group that kills regto and did sum other stuff with Amo that I can’t remember. Also do you think there is only 2 of them or are they a group I think it’s a group probably because I don’t see tamsy being the like final boss he seem more of a high ranking member of a group or right hand man. Speaking of like future villains and what not I think the hell guard might become a antagonist for like 1 arc or some even though they are allying themselves with the cleaners currently but I will say though kyouka seems very protective of Zanka so if they do become antagonist I wonder how that will play out
