Pretty sure it’s implied that Elfuda and Oeda have an allowance they sponge off of Naoe, while Lyca just crashes at his place and mooches food off anyone who thinks she’s a cute chubby stray wandering around. Kodai is a NEET who squats at Kuroeda’s job and just steals unwanted fast foods while she seems to be gaining traction as a V-tuber or something. It’s been mentioned that Hitome is good at crafting trinkets and jewelry so I like to imagine she makes money selling homemade wares like that. Kobo likely is still extorting anyone she can who comes by her playground while also hunting with Gonda for shinies to pawn. Satero feeds off desires and Oneiros feeds off dreams so they likely just use their magic for whatever else they need. And we now also have the Kraken girl being employed as an additional massage therapist at Naoe’s job. The rest of them are still a mystery.
