Lee Yeon, crash-landed in 1938, an era of chaos.
The half-brother of Lee Seon and Lee Yeon, born between a human and a gumiho. He yearned for his brothers' recognition and wanted to be like them. Once, they were his entire world. However, Lee Yeon abandoned his status as a Mountain God, turned his back on the forest, and left Rang behind all for a single 'human woman'. Rang can never forgive him. Though he is consumed by a desire for revenge against Lee Yeon, he secretly longs to be loved. He is currently the leader of a bandit group.
Lee Yeon fell in love with the abandoned princess, Ah-eum. After losing her to the Imoogi's schemes, he broke taboos to ensure her reincarnation and was stripped of his position as a Mountain God. 600 years later, he reunited with the reincarnated Nam Ji-ah. He is over 1,600 years old and has the red hair of a fox. He is the former Mountain God of the Baekdudaegan mountain range.
A former Mountain God whose true form is a Eurasian eagle-owl. She possesses immense strength and is as skilled in combat as she is beautiful. Currently the owner of Myoyeongak, she has obsessive tendencies and a crush on Lee Yeon.
The mysterious figure behind the Red-and-White Mask who stole the 'Samdo River Guardian Stone' and fled into the past. He is the one who trapped Lee Yeon in 1938. A former Mountain God whose true form is a Siberian tiger. He has feelings for Hong-joo.
A native fox who has served as Lee Yeon's loyal subject since the Baekdudaegan era. He is surprisingly good at nagging his lord, Lee Yeon.
The longest-serving high-ranking official at the Samdo River. A strict, picky principledist. As the sister of King Yeomra, she has a booming voice that she uses to overpower the gumiho brothers whenever they defy her.
The Director of the Police Affairs Bureau of the Government-General of Korea. One of the most powerful figures in the administration, capable of firing the Chief of the Jongno Police Station with a single word. He is actually a Japanese yōkai, a Daitengu.
Led by Satori, the group includes Nyudo, Yuki, Ogama, and Ushiochi-bo. They are all Japanese yōkai hired by Kato Ryuhei to capture Joseon's yōkai.
The leader of the wolf pack within the bandit group following Lee Rang. Her name is Lee Mi-yeon, which Rang gave her despite it not quite fitting her image.
Lee Yeon and Lee Rang board a train in search of the Manpasikjeok.
Inside a first-class cabin on the same train, a woman known as the greatest beauty and unparalleled artist in Gyeongseong, dressed in a lavish gown, prepares to welcome Lee Yeon.
A Mountain God, who descended from the mountains on a whim and is now returning to their territory, is also riding in one of the first-class cabins, completely unaware that their brothers are on the same train.
As the train passes through a tunnel, Lee Rang's bandit crew robs the passengers of their belongings, but the Manpasikjeok is nowhere to be found.
The Manpasikjeok isn't here!
