Gender: Female A 2nd-year student at Gaon High School. She used to be an archer but seems to have quit. She was once very close friends with Rather and Yedam, but as she began participating in national archery competitions, she couldn't spend time with them, leading to a rift. Following Yedam's death, she and Rather effectively cut ties; they are now awkward around each other, and Rather often walks away when she tries to speak. However, they both seem to harbor some lingering affection and worry for one another. She struggles to mediate between the constantly bickering Gakbyeol and Chouchou, sometimes getting caught in the crossfire. She uses polite speech with Gakbyeol, Chouchou, and Suhyun.

Gender: Female Successor to the Dragon Clan. She came to the human world to take the test to become the Dragon King and stays at Sleepground's house. She is highly distractible, prideful, and selfish. She frequently bickers with Gakbyeol and seems to despise the Imugi, Coa. She can manipulate surrounding water, purify polluted water, and protect specific individuals. She also appears to have the ability to make it rain. When transformed, she becomes a massive blue dragon invisible to humans (except Sleepground).

Gender: Male The former head of the Tiger Clan. In contrast to Chouchou, he is very serious and polite, though his personality occasionally shifts to resemble hers. He can transform into a large tiger invisible to humans and wields the power of fire.
