Shisan Meihua

As the thirteenth daughter of the legendary Plum Blossom swordsman, this masked anti-hero operates as a lethal, mysterious assassin. Though she initially presents a cold and prideful exterior, the loss of her mask reveals a flustered, vulnerable side that struggles to balance morality with her deadly training. Her detached persona often shifts into a classic tsundere reaction whenever Seven attempts to flirt with her, creating a playful tension during their frequent encounters.
