Tale of the Nine Tailed - Season 1 (2020)

Yeon and Ji A wake up to see the island empty. All of the villagers vanished without a trace. They return to Seoul only knowing that a mysterious baby was born the night before. Yeon faces a trial for killing the shaman, and Rang pays a visit to Ji A.

Yeon has finally found A Eum. But he doesn't tell her the whole story as he wants her to live as human in this life. Then they set off to look for A Eum's parents. Yeon finds out that the governor has something to do with the disappearance of her parents.

Yeon and Ji A go to the Korean Folk Village to look for the governor. The governor refuses to give information on Ji A's missing parents, and he starts attacking Yeon. Meanwhile, Rang is at the Korean Folk Village, looking for the item that let one see their past life.

The Imoogi that has been reborn starts approaching Ji A and Yeon. Yeon barges into Ji A's house to stay and protect her at all times. In the meantime, Rang loses the eyebrows of a tiger and asks Yu Ri to find it.

Ji A sees her past life and how she was killed by Yeon. The two turn cold towards each other and Yeon dares not approach Ji A to prevent history from repeating itself. One day, a mysterious woman appears at the Snail Bride restaurant. She asks the same one question to everyone, "What do you fear the most?"

Yeon and Rang trapped in the Forest of the Starved fight the evil spirits endlessly. Meanwhile, Ji A reunites with her parents in her dream and begins to forget her memories with Yeon. Will they be able to get out of the trap set by the Spirit of Darkness?

Ji A shows Jae Hwa and Sae Rom their past lives and ask for their help as she prepares to face Imoogi. Soon enough, Imoogi joins Ji A's team disguised as an innocent intern and starts scanning people around Ji A.

Imoogi tells Yeon that he'll let Rang, Ji A, and Ji A's parents live if Yeon gives up his body. Rang has to choose whether to kill himself to save his brother, or to kill his brother for him to live.

Ji A finds her parents and Yeon is more than happy for her. But they still have to get rid of Imoogi. They find ways by researching all kinds of folk tales, myths, and stories. Imoogi keeps attacking them by secretly approaching them.

The other Imoogi inside Ji A's body woke up. In order to end this long fight without hurting anyone, Yeon comes up with a plan of using the Sin Slayer. Yeon, Ji A, Rang, Shin Ju, and the Snail Bride work together to get rid of the Imoogi.

Taluipa changes Ji A's death date. Yeon begs her to give him some time to catch Imoogi. Meanwhile, people start dying of a strange disease that spreads fast. To stop Yeon from sacrificing himself, Rang comes up with a plan.

Yeon teams up with Immogi without knowing that Imoogi is plotting something against him. Yeon thinks he can put an end to everything and save Ji A by eating Imoogi's scale himself and jumping into the Samdo River with Imoogi.

Ji A is in despair after watching Yeon jump into the Samdo River to save her. Ji A and Rang meet the King of darkness who is one of the afterlife judges. He suggests that Ji A or Rang should sacrifice their life to bring Yeon back to life.
