Wait, ghosts can have children now?! Since when? I thought spirits couldn't have babies because they're, well, spirits, and so they adopted other souls into their family, like Rukia or Renji. Only now we discover that they can have babies?SS is just like the Human Realm, you can die, get sick, etc. You can even get pregnant (Byakuya, Yoruichi, etc. are all born there). Rukia was adopted just 'cause she was Byakuya's sister-in-law. And AFAIK, Renji was a commoner, meaning he was born in SS.
If you die in the Human Realm, your soul either becomes a Hollow or you go to SS and are given the body you had before you died (like virtuous souls in DBZ).
