One day after the -3rd anniversary of the Second Impact, my third fic.
And, surprisingly, it's a take on the events surrounding the second
impact. 

Is Sept. 13 an official date?  It's the same day the moon broke away from
Earth in Space 1999 and Otaku no Video....

Really? Anyway, yes, it is official. 

Second Impact 9/13/2000
Indo-Pakistani nuclear war 9/15/2000
Tokyo is destroyed by the first N2 bomb 9/20/2000
 
And to bust a preconception, Touji was born 12/26/2001, ~15 months after
the second impact.

Let's hear it for freeze frame (and the manga.)
