Okay I have finished this and have two questions:
1.Who was the one told Ryuuseii about using the box on Shiki family/chasing after him at then end? From what I read the fan theory was that it's Yasaka Io but felt kinda random and out of nowhere. Was she the one who pay for Nozomi's hospital bill too? And set up the whole story because she wanted to see Kurou developed into "human" or something?
2.What's with two Nozomi at the end? One was story/heroine Nozomi and the other was the new one born from the box at the end?

3.So the reporter was the second Nozomi's descendant? Did he was basically interviewing his ancestor? Did she give him the box so that he could repeat the process and "birth" another generation of "Nozomi"?
