If there's a big, shadowy corporation in the background, why not make them less generically corrupt and more well-intentioned extremists?  Like... Well, I at least know that Double will know what I'm talking about if I say Yggdrasil at least. XD ...Thinking about it, Zawame City is basically a good idea of what I would go for in terms of setting, but hmmm.

And... I dunno, maybe it's just me that thinks this but any kind of social commentary in this should probably come from the plot focus (ie. the metahumans) rather than any existing corruption really. ^^;
