Remove the "shouta" tag because having one of your protagonists be a kid is VERY different from being shouta, dear fluffy lord...
(And added the obvious "sci-fi" tag. And I'm pretty dubious about the relevancy of the "gyaru" tag; she might be one but the story doesn't really care about that, I think, but I'll leave that one alone.)
...In other news this is seriously some ambitious stuff so far. Not sure if we're starting a sci-fi epic, or a world-building-heavy SoL with occasional heavy action, or what, but whichever way, count me in.
