She very clearly isn't the Shinju, as it existed long before she ever came from wherever she came from, and exists completely separate from her. That also knocks out the creation theory, and your theory of her becoming the Shinju.

The reason she claims chakra is hers is because she was the original and only user before her son started handing it out like hotcakes. She feels entitled to it because of that, thus her arrogant statement.

As for the rest, I have no comment.
