The 'world' the game took place in was the kind of place where kids don't get a name until after their 10th birthday, because they could break out with 'Plague' before then, that gets them taken away from their families, and they are considered as good as dead at that point. Why name someone who might not survive childhood?

'Plague Bearer' was what they called kids like that, and all of their society's undesirables. And I learnt a lot of fucked up stuff involving them. Like how the military is the only place they can work in legally, kids -- [ He pauses, and swallows. ] -- getting sold to nobles. For unimaginable shit.

... Maybe this isn't the same 'setting' as the last one, but I wouldn't be surprised if Venus thinking 'exile' is how the way to go is because that's really how things are done, here.
