Callie is the marquee star of the La Ventura arena.
In the deep-sea city of La Ventura, there are plenty of attractions, but none compare to the arena. The arena's battles, where both blood and sweat are shed, offer an unparalleled spectacle and have become the signature tourist attraction of La Ventura, which draws people solely for that thrilling event. As the face of the arena, Callie is extremely popular thanks to her exceptional fighting skills, dazzling looks and showmanship.
Callie's life before her wrestling career remains a mystery, even to Callie herself. Her earliest memory is waking up alone in a dark, abandoned ruin. It was thanks to the village elder of the slums who first discovered her 5 years ago that she was able to step out into the world. Even after leaving the ruins, Callie's life has been anything but easy. To someone with no memories or knowledge, life in the slums, where failing to pull your weight meant going hungry, was an unforgiving environment. Callie wouldn't be here today without the people of the village, who helped her become a valued member of the slums.
To her, the people in the slums are as good as family. In the same way they helped her, she has always believed that it's her duty to be of help to them. Even as a marquee star who earns vast sums of fight money with every fight, Callie still lives in the slums and devotes most of her earnings to supporting her community. She remains there because it's more than her home, and because she wants to protect her family.
In the city, Callie's level of fame is unmatched, even by most celebrities. Her die-hard fans even try to mimic her every move. However, there's one thing that even they have given up on: her taste in food. Callie's favorite dish is a triple cheeseburger, always ordered with no pickles and extra cheese. Most people can't even finish a bite because of how greasy it is.
