Teenage Human Penjaga. Her Mom disappeared and her dad's been checked out since she was young - she's been doing her best to fill the gaps. She has given away a lot of herself in the process.

screenname is from Your Inception by Joel Baylis:

If you learn to loosen your mind
You never know what you might find 'round here
The box looks smaller from the outside
Holes that they made will cave in
A dream of filling boots too big
In time you’ll see
How brave that you need to be
