actually if it snow or rain in space snow would be the more likely since its supposed to be really cold up there well when u think of it ''human hunting'' goes along with the cannibalism in the pretty out there factor
Dude, they're on a sentient steam train that flies through space. Is "snow in space" or "justified cannibalism" really that much more of a stretch? lol.
Talk about Japanese version of Soylent Green. At least, Leji's story was quite blunt of how to go about it. The Twilight Zone tv episode 'How to Prepare Man' is probably inspired him to have that story made.
