Alternative Character Idea: Rinku or Shina Tsu Hiko (haven't decided on namez)

[Belle Hibiki]

Is that thing about Kaishin and Kaiju trees canon? I don't really remember that stuff.

I only ask because it might contradict what I've been doing in my story - namely that when a Kai dies, it is replaced by a suitable candidate from the mortal world that's been born with the 'gift' of possible ascension.

Otherwise doesn't seem like a bad idea.
