Su Yuan traveled through the world of Dororo and was born as the legitimate daughter of General Daigo. On the day of birth, he was struck by thunder, the Bodhisattva was beheaded, and he was born with the curse of the devil. He became a sacrifice for his father's trade and was abandoned right after he was born. From then on, in troubled times and desperate situations, he defied nature and broke free from the shackles of fate.
