A good number of years ago (at LEAST five) I was flipping through the channels late at night and came across a GOOD but dark anime film. I was only able to start watching it about 1/3 of the way into the film I guess. I missed the start. I was never able to find out the title of the movie or when it was made. I really want to see the start.
It's about a brother and sister who survive an atomic bomb. I remember a scene when it rained black... then later on the little sister got very ill and had bruises/blisters all over her body... (the girl played around in the weird rain)



Wow,

So if anyone knows the name of this film, who made it, what year, etc, can you let me know??
Thanks a bunch!!
