Okay, so they can rape a man until he becomes a god. Completely reform a high school boys body. And make an almost perfect clone of a fully grown woman, but stopping a gunshot wound is outside of their abilities. Yes I realize they were in the middle of a forest, but they are right next to medical equipment in the cave they were hiding out in.
Besides that, what about Kinebuchi's baby (#4) that he had shortly before going into cryostatis with his wife? (chapter 44) I guess that part will get covered in part 2 along with all of the other plot points that were brought up and then dropped, such as Reito's brother who was confirmed to be a number and Doi's teacher/first lover who was sequestered and protected by Karen. There are far too many plot threads in this story and I doubt a second season will be able to successfully pull everything together.
