   Summary

   Pre Canon Family building with an OC sibling that is kind of a self insert, but not really.

   Nico wasn't always a Turtle but that doesn't matter right now. No, right now all they want to do is help their new Family not die in the streets.
   (First chapter is kind Of an intro for the Charakter)

   I couldn't find any content with more siblings, so I made my own.
