Rather short :S
Nonetheless, if you chose to expand on this story, there is much potential.
Right now, the story doesn't really capture me. One thing to keep in mind when expanding is sentences like:
A few days passed on the ship, and then the TV and radio went dead.
What happened in those few days?
Why did the TV and radio go dead?
Where was he traveling from?
These and more answers to several more questions can help to engage the reader, and add to the general atmosphere of your fic.
We eventually arrived at our destination: Kanto. As we stepped off the ship, smoke filled our nostrils.
Perhaps here you could not only work on the mood of the situation, but also the continuity problem. Like a sense of fear or an ominous disposition.
That is, did they just notice the smoke after getting off the ship? I would think they might be able to smell it from quite a distance, never mind the fact that they could probably see it billowing in the sky.
The city was destroyed. People laid on the ground, dead.
It's a comma because 'dead' is not its own sentence as is the purpose of the semi colon.
Also, describing the wreckage and devastation would be a great bonus, as well as your character's reaction. Perhaps he saw mangled bodies and threw up at some point.
Otherwise spelling looked alright, and grammar looks okay.
Also if you figure that this fic would be more appropriate for a more mature audience, be sure to clarify it at the top of your fic.
