Age: 29 Height: 187cm Appearance: Has red hair and red eyes. Personality: Cheerful and very playful. Characteristics: He has been the butler of the Park family since he was young. He is someone Sleepground trusts deeply. He always carries something for discipline, but he doesn't actually hit anyone; he only uses it for intimidation(?). Honestly, while Deokgae is the bodyguard, Rader has a good physique, so he occasionally serves as a bodyguard as well. He is both a butler and a teacher. He teaches Sleepground her studies. Uses polite speech to everyone. Belongs to a different family from Gongryong and is in the same family as Sleepground.

Age: 27 Height: 189cm Appearance: Has orangey-beige hair tied in a ponytail. He has squinty eyes and is a dog beastkin. Personality: Gentle nature. However, he does not hesitate when it comes to protecting Sleepground. Characteristics: He is the bodyguard of the Park family. He always carries an orange pistol. It's usually loaded with BB pellets for playing around, but he switches to real bullets in times of danger. His marksmanship isn't exceptionally good. In the past, he belonged to another family with the dream of succeeding in the city, but he was kicked out after taking the fall for his master's crime. While he was sitting leaning against a building in the rain without an umbrella, Sleepground passed by, found him, and took him in as her family's bodyguard. Uses polite speech to everyone. Belongs to a different family from Gongryong and is in Sleepground's family.

Age: Unknown Height: 178cm Appearance: Yellow hair and yellow eyes. Personality: Playful and laid-back. Characteristics: He died a long time ago. However, due to his past playful personality, he was sealed away in the room where Soohyun teaches magic to Gongryong in the Jeong family mansion. Since the seal was broken, he follows Gongryong and Soohyun around every day, teasing them. Since Soohyun isn't really affected by it, he teases Gongryong the most. Belongs to a different family from Sleepground and is in the same family as Gongryong. Soohyun was also Gakbyeol's tutor in the past. Gakbyeol's form is invisible to most people and can only be seen by those who use magic. It is presumed that he was very skilled at magic in the past. He was a young master of the Jeong family. Uses informal speech to everyone.

Age: 9 Height: 143cm Appearance: Brown hair and black eyes. Personality: Playful. Very talkative. Characteristics: Young master of the Jeong family. Although it's a magic family, he isn't very good at magic. His family is close with Sleepground's family. Gongryong hates magic lessons and runs away every day. Unlike Soohyun, who can use magic instantly with a staff, he has to use individual scrolls to cast spells one by one. Soohyun carries the scrolls and gives them to him one at a time when needed. He trusts Soohyun. He has a hard time because Gakbyeol teases him a lot after being unsealed. However, he doesn't completely hate Gakbyeol. (Meaning he still dislikes him, though.) He is more talented in academics than magic. Uses polite speech toward Rader, Deokgae, and Gakbyeol. Belongs to a different family from Sleepground.

Age: 9 Height: 140cm Appearance: Long brown hair and black eyes. Personality: Bright and cheerful. Very talkative. Characteristics: The young lady of the Park family. Unlike other noble girls who are calm, Sleepground loves exercise and physical activity. Because of this, she often tries to ditch her studies and sneak outside, only to be caught by Rader many times. She trusts Rader. Her family is close with the Park family. After learning about the magic of Gongryong's household, she sometimes takes Gongryong's scrolls and uses them. She might seem dim because she doesn't study much, but she is naturally quite intelligent. Uses polite speech toward Soohyun. She doesn't get along well with her rival, Rona. However, she doesn't completely hate her either. Belongs to a different family from Gongryong.

Age: Unknown Height: 176cm Appearance: Black hair with a purple tint and orange eyes. A rabbit beastkin. Personality: Calm and gentle. Characteristics: Carries a dedicated staff. He can use magic instantly and is the tutor for the Jeong family. Since no one without magic power can serve as the tutor for this house, he seems to have been doing it for several hundred years. He was caught by the Park family for being from a magic household, but he knows they won't spread the word. So he is at ease. He was also Gakbyeol's tutor once. Uses polite speech to everyone. The Jeong family has a rule against physical discipline, so he doesn't hit. (He does intimidate, though.) Belongs to a different family from Sleepground and is in the same family as Gongryong.
