How Age Note works

Age Note is off the idea of the anime Death Note. Death Note is a book where when someone's name is written in this book they will die as long as the writer has a picture of their face and has their legal name. This will be along the same idea where a persons name written in the Age Note will change ages as specified when their name is written down in it.
This story will be written in first person as you who are reading are holding the Age Note
