Monsterverse AU (no angels)
Phoenix!Michael: the last of his species and the only monster that can destroy Eve (canon). Mommy issues galore. Probably killed all the other phoenixes in an attempt to show Eve how good of a son he is. Wants to free her from Purgatory. He's part of one of the oldest species of monsters on Earth, but it doesn't necessarily make him wise. He's almost immortal and can turn into a giant flaming bird (and a pile of susuwatari/sentient soot, if he gets "killed")
Siren!Lucifer: like canon Sirens, he doesn't need to feed off humans. Some sadist Sirens mess with humans recreationally, because they get an intense rush of pleasure when a human becomes entirely devoted to them and commits crimes for them, which is easy thanks to their venom... But Lucifer is tired of games and artificial love. He wants to inspire true passion in someone. The intensity of Michael's devotion for Eve makes him deeply envious...
Kitsune!Raphael. When they're not napping all curled up in their adorable fox form (often on Michael's shoulders, wrapped around his neck like a scarf), they're hunting for human brains. Or at least, they used to. Now, they work at the local morgue and can easily get a fresh supply of pituitary glands. Like any fox, they're basically cat software running on dog hardware (also. fluffye). They don't have nine tails, as they only get an additional one every 100 years. It is said that kitsune who reach 1000 years of age will become tenkos (天狐, 'heavenly/celestial fox'), but as far as they know, no kitsune has ever survived that long...
Shapeshifter!Gabriel. Master trickster, always running from his problems by taking on a new identity (but when he bites off more than he can chew and angers the big leagues, changing skin isn't enough to be safe...)
And they're roommates à la apartmentverse 🥰
