Half the Giant You Are

Name's Jack. Call me Jackal.

Three or so years ago, some cosmic entity decided to spray half the planet in radiation. For some reason, possibly diet or genes or something, it really only affected the College Student Population in Japan.

And, only partially, me. An American. The only American, oddly enough.

The radiation didn't really cause any adverse side effects other than sudden and extreme growth in general.

So Japan quickly became way overcrowded by giant women accidentally trampling people.

As such, we got Australia.

The Australians were understandably not to happy about the sudden influx of giants and quickly relocated to anywhere else, leaving Australia to be basically a giant-only country.

Back to me now, I was simply walking down the street at the time when I was decked by the rad wave out of nowhere. I woke up a week later occupying the entirety of the street and the government guarding my new giant body.

A few months later, after all the extensive paperwork, procedures, and bargaining, I was allowed to stay in America until my 18th birthday because of my doubly-unusual height.

I had thought I was already pretty huge, rounding up to the point that I could reach my hand over the Empire State Building if I really wanted to, until they told me the Japanese ones were twice my height.

So... I was kinda screwed. Maybe literally.

Did I forget to mention there was like a twenty-to-one female/male ratio?
