i mean-omg okay so i have a theory about their ages in the celestial realm, bc they said their order was diff because of when they fell. So heres my theory (satan is obvi the youngest so i’ll just be doing the other six + lilith, cause we know satan-)
Lucifer: oldest. I. Obvi.
Beelzebub + Belphegor + Lilith: (they’re v close in age) next eldest, beel to me just seems v responsible and so does belphie
Asmo: okay hard to choose between asmo and levi but levi still acts wayyyy worse than asmo sometimes. Asmo is definitely a middle child
Levi: this boy literally threw a temper tantrum when he lost to MC in the trivia game, so. Yeah
Mammon: this boi just acts like i do, and im the youngest. Constantly defies authority and is super immature, and uses his power as the older brother now, probs cause he got a lot of crap from the older brothers in the celestial realm
my theoriesss and then satan is the youngest ofc ofc but he’s v responsible
