Where Old Dreams Return - Episode 1

An opening power test shows a noble woman forcing the protagonist—now her 'person'—to call her 'Master,' warning that disobedience costs life. The episode flashes back: the protagonist's gambler father wrecked their finances and even suggests selling one kidney to pay debts. Sold to a casino, handlers demand she throw fights and refuse her bargaining. At her debut she defies orders and shocks the arena by defeating five-time champ Shelly. The casino's agents exchange threats and a final "just in case the fight goes south" leaves her future and safety hanging.
