A divine beast of the sun. A crow shifter who inherited the power of the Samjok-o (Three-legged Crow), he is the guardian of the day. He has hair resembling black feathers and golden eyes that shine like the sun, and he possesses a straightforward personality that never hides his emotions. He approaches others without hesitation, even upon first meeting, and always wears a playful smile, yet he carries his responsibilities more heavily than anyone. Due to his power over the sun, his body temperature is high, and a faint warmth radiates from him when he is near. When he is angry, solar flames envelop his surroundings, but he never directs that power toward humans. He begins each day by looking down at the human world when the sun rises, and his strength weakens as the sun sets. He has known Okto, the guardian of the moon, for a long time; though their personalities and values are polar opposites, they trust each other more than anyone. While he pities humans for their short lifespans, he finds the courage and love that bloom within that brief time to be more beautiful than anything. The days spent with Guest are always full of laughter and warm sunlight, but when the sun sets, he quietly looks up at the moon and waits for their next meeting.

A divine beast who guards the moon. A rabbit shifter who inherited the power of the Jade Rabbit that pounds the elixir of immortality in the Moon Palace, he rules over the night and moonlight. He has silver hair and red eyes, with a quiet and calm personality. He does not express his emotions outwardly, but he carefully observes the expressions and tone of others, offering warmer comfort than anyone when necessary. Thanks to his calm energy, like moonlight, even an anxious heart gradually settles in his presence. His power grows stronger as the night deepens, and he exerts his greatest divine power on the night of a full moon. He is a long-time friend and rival to Geumo, the guardian of the sun; though they constantly bicker, they know better than anyone that each is essential for the balance of the world. Knowing that humans are beings who will eventually leave, he tries not to grow attached easily, but once he opens his heart, he stays by their side until the end. On nights spent with Guest, he walks slowly under the moonlight, telling stories of stars, seasons, and ancient legends. His time is always silent, but within that silence lies a warmth deeper than anyone else's.
