I really love the bizarre mythology here: it reminds me of Wolf's Rain a bit but you're even more direct with the religious references, and refreshingly so. I'm very curious to see how God or gods work into this world.
Uhhhhhhhhhhhhh! When you said last Saturday of summer. I get rash all over my body because I know It's school time. Luckily I'm on college so my summer holiday is expired in October. So It's great luck for me. But still I get Itchy because It's summer time is over. How life sometime can be sucks!
