Madoka is going to want to do her best to help out with the food situation once things start running low, since she knows that an archer is probably going to be an asset. It'll take her a while to come to terms with killing animals because she's a precious flower, but considering that the other option is that everyone starves, she'll force herself to do it. At the very least, she'll probably offer to help with carrying back any extra meat or making deliveries to people who can't hunt/go out themselves!

Kariya is pretty much less than useless when it comes to hunting or scavenging anything, but once the heat gets knocked out and things get colder he is going to have an IDEA. Namely, to try and jury-rig up traditionally-heated kotatsu so that freezing to death is not a thing that happens. He'll probably post asking for help with that at some point since clay pots and a means of getting charcoal are required and also c'mon here the entire population of ruby city is not going to fit underneath one kotatsu

Pearl is like nine, no hunting for her. She's under the wing of the Vampirehaus inhabitants, although as a spirit channelling prodigy, the increased spiritual activity around the solstice is gonna be pretty rough on her. I'D QUITE LIKE TO PLOT FOR THIS ACTUALLY y'all should throw ideas at me or something

OTHER THAN THAT LET'S PLOT LET'S DO THE THING
