inspired by this post that honestly depicts the dynamic of how I have my OC's interact with Beleth and Agares is c r a z y.
Astra's go to devil when in Nifelheim is Agares, their chemistry knows no bonds, and Agares is in fact infatuated with her that it shows on his face when he least expects it. He doesn't know what to do about it except for doting on her and being real sweet on her. In private, he doesn't want Belphie to see him like that.
Nova and Beleth are quite the pair, and he wouldn't have it any other way. Sure he's in a polycule with them and Belphie, but his two favorite people? His cup runneth over. Nova is originally from Avisos so adjusting to Nifelheim has been a culture shock for them. Beleth holds their hand, gives them enough love and he gets it back. He wouldn't have it any other way. Now since he does know about their previous relationship with Andrealphus, he may get a bit jealous here and there, but it's nothing but a quick thought.
Id love to hear more about your interpretation of the sins
EDIT THIS IS SO OUTDATED IN TERMS OF SATAN + BEELZEBUB RIP
heres the family dynamics! + some notes
- the 7 kings are still fully in charge of everything while their kids are mainly just weird celebrities who do projects sometimes that the kings dont want to
- satan, asmodeus, mammon, beelzebub and leviathan have other kids but these are the one they dub as their heirs even tho theyre not dying or retiring ever. lumiloriol is the only child of lucifer that just kinda a part of a solar flare off of his radiant light once and then was taken in by satan. belphegor made dumois bc they felt like they should have at least 1 heir but dumped her in some estate and never visits
- further clarification for the lucifer/satan thing, its inspired by paradise lost where the demons are turned into snakes for a few days every year but they get to be fallen angels most of the time, but i thought itd be interesting to switch that since theyre supposed to be punished, so instead satan is active most of the time and lucifer emerges from his body like a chrysalis for a few days a year before he has to go back in. satan is lucifer in that he was him and then was corrupted, he did all that shit, its just that lucifer is also preserved inside of him if that makes sense. so like satan is lucifer but lucifer isnt satan. hes still evil tho obvs
- i only have a designated second parent for concupiscence bc ive liked the idea of asmodeus and beleth being a thing for years now plus asmodeus needs gay dads. aureus and gaglug are also born from consorts of the princes, but the other four were born just from their one parent
