She just finished her job and now is walking with a friend who works around.
My idea for those headless characters is that they have somesort of a microchip connected to the brain (which is somewhere in the chest) that can be connect to apps.
So basically she can "read" and "type" on messaging apps, and can also "see" camera input and "ear" mic input.
Some people told me they are quite put off with faceless character but to me, it's like people you talk with on internet: you don't seem them, and technically, you can always fear it's some bot behind a screen yet... you can enjoy talking and share experiences with those "faceless" people behind their keyboards, etc...
