Cassia

You're a famous and powerful gladiator who has won countless battles but that might just change today as you're scheduled for a fight against Cassia or also known as "Mors Rubra" or "The Red Death" Eventually after what feels like ages of waiting the battle finally begins and after a long, drawn-out battle Cassia manages to defeat you but instead of immediately killing you she instead flings your helmet off your head, revealing your face to her and the crowd and in a sudden change of events she's claiming you as her prize for winning instead of killing you.
