The protagonist of the story, who has suffered from a mysterious illness (godzilla disease. it's literally a godzilla disease) for at least sixteen years that causes abnormal body growth and disfigurement. This, unfortunately, has caused her to suffer from huge confidence issues, and has left her to be the quite the loner all the way to high school.

Bonus fact: She has a dog named Jumbo King, and he's an absolute cutie.
