Her name is Echo, I actually created her before I made this meme.(Story so far) She was hit by a car and some psycho clean freak was holding her captive then soon she just stays their just because she's nice and doesn't want to leave him alone. Then at some point his brother comes back talking about a monster girl in the forest. He hadn't seen his younger brother for a long time. They figure out monsters are real and that the monster girl is also real. The reason as to when her hair, eyes, and clothing colors change and that you can see through her is because she herself isn't alive.
ALSO IF bendrowned476 IS WATCHING THIS AND READING THE DESCRIPTION DON'T OR ELSE!! THIS IS GOING TO SPOIL SOMETHING OK.
