I'm sorry, but I don't care if you're a kid or not, that is a VERY bold thing to scream in the middle of the streets, even if you know the people you're directly talking to. Especially with where they are. Basically saying "there's a meltdown!" while you're in a nuclear power plant.
Okay just reread a couple chapters back, Straus is the woman they're looking for.
Also, I know it's a little thing and it's basically the point of the whole setting, but I love the idea of a place being called "City of the Previous Century" being the most futuristic one. This manga has such good world building man
