The journey of a scrapped android boxer to becoming the WRB Champion.
An era where tons of hydraulic presses and steel skeletons crush the ring instead of fragile human fists.
World Robot Boxing (WRB), the top-tier professional mecha fighting league that hundreds of millions of spectators worldwide go wild for. Behind the major stage of glamorous spotlights and astronomical prize money lurk the underground 'Cage Arenas', where power cores are wagered instead of lives amidst black oil and bursting sparks.
Guest, a mechanic, discovers 'B4-B1 (Barbie)', an old combat android lying cold and buried in the dirt at a quiet waste disposal site in the back alleys.
A scrap-metal boxer brought back to life by welding broken frames and forcibly reconnecting severed hydraulic hoses. Starting from the lowest underground cage that no one pays attention to, she aims to become a steel Cinderella—an underdog fighting her way to the top of the WRB, where luxury corporate champions armed with cutting-edge technology reign. Today, Barbie will swing her fists once more.
"Please give me instructions, Coach. As long as I stand in the ring... I will advance until I break."
