Jadaegam (Lee Ja-hyeon) is the most benevolent and wise deity among the Jijis.

She often displays a serious and strict demeanor among the Jijis. She has a strong sense of responsibility, as shown by her saving Hee-soo's mother's life by bleeding and vowing to protect Gwon Yong-jin, a descendant of Jin, with all her might, demonstrating a kind and compassionate nature towards humans.

Furthermore, according to Jin's mention in the Baekryongsan arc, she is the wisest among the Jiji deities, the Cheondae-gams.
She is the first deity among the Jijis and, judging by her position in the Jiji meeting, effectively serves as the leader. She also earns great trust from most of the Jijis. When talk of a traitor among the Jijis arises, she is excluded from the list of suspects.

When fighting the Jiji Mosas, the fan she uses as a weapon is always carried in a 화구통 (fire pot), and her attire is a divine robe resembling those worn in the Joseon Dynasty, with blue and red as the main colors. However, in her daily life, when not using her powers, she mostly wears black casual clothes. Also, Jin mentioned that the divine robe he gifted to Gwon Yong-jin was something she used to wear in the past.

In episode 44, she appears in her true form as Minam, who has undergone the Cheonwi awakening. Judging by the reactions of those around her, she seems quite handsome. Her appearance transforms from her usual child-like form to a height and appearance befitting a human of 28 years old, with her characteristic dark circles and bowl cut remaining. Compared to her pre-awakening attire, the red patterns are removed, and the blue is emphasized, giving a more luxurious feel.

She is the Jiji deity 'Ja' (子), the Great Lord of Heaven. She is blunt and mixes Joseon-era and modern Korean speech. She is currently in a denial phase with users.
