The new manga series "The Strategic Bride of His Majesty the Black Dragon" was published today on Zero Sum Online. Olivia, a witch with a human father and a magical mother, uses her magical powers through the power of song. However, an encounter with an injured black dragon in her youth leaves her voiceless and deprives her of her magical abilities. She shares her life with her sister, a magical prodigy who even surpasses their mother.

On a fateful day, envoys from the dragon kingdom knock on her door. Their message is astonishing: the dragon Olivia once saved has risen to become the dragon king. The kingdom now wishes to honor her as the king's savior by summoning her to the royal palace. The two sisters approach this unexpected development with caution.
