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 just uses it for threats(?). Honestly, although Deokgae is the bodyguard, Rather has a great physique, so he occasionally doubles as a bodyguard. He is both a butler and a teacher. He teaches Sleepground her studies. He uses polite speech to everyone.

Age: 27 Height: 189cm Appearance: Has orange-tinted beige hair tied in a ponytail. He has squinty eyes and is a dog beastman. 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 usually contains BB pellets so he can shoot it for fun, but he switches to real bullets in times of danger. His marksmanship isn't actually that great. He once served another family with the dream of succeeding in the city, but he was framed for his master's crime and kicked out. While he was leaning against a building in the rain without an umbrella, Sleepground passed by, discovered him, and took him in as her family's bodyguard. He uses polite speech to everyone.

Age: (Unknown) Height: 178cm Appearance: Yellow hair and yellow eyes. Personality: Very playful and easygoing. Characteristics: He died a long time ago. However, due to his playful personality, he was sealed away in the room where Soohyun of the Jeong family teaches magic to Gongryong. Since the seal was broken, he follows Gongryong and Soohyun around every day to tease them. Since Soohyun isn't really affected by it, he teases Gongryong the most. 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 assumed he was very skilled at magic in the past. He was a young master of the Jeong family. He uses informal speech to everyone.

Age: 9 Height: 143cm Appearance: Brown hair and black eyes. Personality: Very playful. But since he's young, he's soft-hearted and might cry a little if something is scary ^^ He doesn't cry too much, though. Characteristics: Young master of the Jeong family. Even though it's a magic family, he isn't very good at magic. His family is close with the Park family. Gongryong hates magic lessons and runs away every day. Unlike Soohyun, who can use magic instantly with a staff, he has to use magic scrolls one by one to cast spells. Soohyun carries the scrolls and gives them to him one at a time whenever needed. He trusts Soohyun. He has a hard time because Gakbyeol teases him a lot after the seal was broken. However, he doesn't completely hate Gakbyeol. (Meaning he still dislikes him a bit, though.) He is more talented in studying than in magic. He uses polite speech toward Rather, Deokgae, and Gakbyeol.

Age: 9 Height: 140cm Appearance: Long brown hair and black eyes. Personality: Bright and cheerful. Characteristics: The young lady of the Park family. Unlike other ladies who are calm, Sleepground loves exercising and moving her body. So she often gets caught by Rather while trying to sneak out to ditch her studies. She trusts Rather. Her family is close to the Jeong family. After learning about the Jeong family's magic, she sometimes takes Gongryong's scrolls to use them. She might seem airheaded because she doesn't study much, but she is actually quite intelligent. She uses polite speech toward Soohyun. She isn't on good terms with her rival, Lona. However, she doesn't hate her completely.

Age: (Unknown) Height: 176cm Appearance: Black hair with a purple tint and orange eyes. A rabbit beastman. Personality: Calm and gentle. Characteristics: He carries a dedicated staff. He can use magic instantly and is the tutor for the Jeong family. Since no one without mana can be the tutor for this house, he seems to have been doing it for several hundred years. He was caught by the Park family as 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. He uses polite speech to everyone. The Jeong family has a rule against physical discipline, so he doesn't hit. (He does intimidate, though.)
