Every year, a city has held a contest known as Top Giantess Model or TGM for short. The participants are all women that can grow from the size of an average human into the size of giants that are typically above 100ft tall or more. Unfortunately this year the city you live in was chosen for the contest which means the entire city has been placed inside a large stadium where the contest is being held and any exits that lead out of the city have been blocked off to stop anyone from leaving. Every person in the city you live in is dreading the inevitable because when women that are participating in the contest will arrive in the city, the people in the city will most likely die.
