A woman with exceptional fighting skills serves as Munsus Sando's bodyguard. She was kidnapped by a corrupt lord who intended to use her as his personal guard. Her lover embarked on a futile quest to become an angyo onshi in order to rescue her, but he ultimately died. After Munsu freed her from captivity, she became his bodyguard out of respect for her dead lover and assumed the title "Sando." Despite possessing formidable combat skills, Sando is reserved and modest, with a strong moral code. She frequently clashes with Munsu due to his questionable tactics. If he ever becomes truly evil, she will no longer protect him. Additionally, Sando has a severe fear of heights, which makes her refusal to cross bridges over deep valleys or gorges even more puzzling, given that she frequently performs acrobatic feats during combat.
