Knowing that the showdown with Keum-ji draws near, Jeaha gets intel on when the sales of the kidnapped girls will happen. But the very presence of those girls makes the fight harder. Until Yona volunteers to go undercover, to Hak's horror.
As Yona and her party begin their search for the Green Dragon, she gets a crash course in the reality of life for the common folk. Meanwhile Su-won visits the capital of the Earth Clan, to the great annoyance of its general.
Trapped after an earthquake, Yona and the others try to dig their way out, with the help of the Blue Dragon. After a lifetime of isolation and hatred, the Blue Dragon finds it hard to believe that Yona is truly his path to freedom.
Hak and Yona take refuge in the capital of Fuga, the land of Hak's birth. But when his grandfather Mun-deok indicates he will not support Su-won's ascension to the throne, the Fire clan puts pressure on the Wind clan.
The search for the Green Dragon takes Yona and the others to the port town of Awa. Hak quickly realizes there is something amiss in the town, and to make matters worse, the Green Dragon seems impossible to pin down.
After being saved by the Blue Dragon, Yona is determined to meet with him again. But when she finds him, he resists the pull to go with her, claiming he is cursed. Meanwhile, the villagers plot to dispose of Yona and her companions.
Yona is welcomed by the people of the White Dragon's Village, who believe her red hair is a sign she is the king they have been waiting for. Of course, only the White Dragon himself will know for sure if she is the real thing.
Hak's massive injuries are treated by Yun, the young boy who cares for the long missing oracle Ik-su. Yun distrusts Yona for being of royal birth, but the oracle dreams of Yona's fate, and points her on a new path.
Having taken a poisoned arrow to save Yona, Hak is cornered and out of options. But a fire is lit inside Yona, and she will not let Hak die. Meanwhile Su-won's coronation day is at hand, and he promises to be a very different king.
To protect the Wind clan, Hak and Yona both decide to leave the capital of Fuga. Mun-deok advises them to seek the oracle for guidance, but Tea-jung of the Fire clan is determined to capture Yona...and kill Hak.
