Love the story, great art. I loved all the cute interaction between Christa and Ymir, especially subtle little things that show that Christa is a closet pervert- like the whole "Ymilk" gag.
Also, did anyone else notice that the two hospital orderlies at the bottom of page 8, seen closing the operating room door, look like Yuho and Shizuma from "Hayate x Blade"?
