Male. He has ADHD and borderline intellectual disability, making him very slow and dim-witted. However, he studies quite hard and has a naive, timid, and kind personality. Kang Gyeong-ja manages the adult Gyeong-tae as if he were an elementary schooler, controlling his every move, showing obsession, and treating him like personal property. His father, Go Gi-tae, left home when Gyeong-tae was 6 and was found dead years later. He has a speech impediment. During the freshman welcoming party, he went to a shop with his mother to buy a magic wand. While the owner was distracted, the owner's cat swapped a normal wand with a dragon-headed magic wand. He ended up buying the dragon-headed wand. The owner sold it at the price of a normal wand without realizing the mistake. (1st Year, Magic Department, Seoul Outskirts University)

A white-furred koala that Gyeong-tae's family is raising illegally. Gyeong-tae and Gyeong-ja mistake Molla for a dog. However, they recently visited a rare animal shelter and learned that Molla is actually a koala.

Go Gyeong-tae's mother and a veteran cleaner with 10 years at Daerim Cleaning Services. She only ever cooks soybean paste soup for Gyeong-tae, never any other side dishes. Due to poverty, she has been evicted by landlords for overdue rent. Despite her financial situation, she severely lacks economic sense and has a poor character. She is habitually power-tripping, a frequent liar, prone to theft, and shamelessly impersonates others while being extremely boastful. She is even foolish enough to have been lured into a cult, much like Gyeong-tae. She is also very meddlesome and prone to making a fuss. Her husband, Go Gi-tae, was found dead.

Male. A professor in the Magic Department. He occasionally makes mistakes with his own magic. He previously borrowed a magic wand from Go Gyeong-tae, but on the first day of the semester, he gave Gyeong-tae his own wand while pretending he had lost Gyeong-tae's. (The reason he pretended to lose it was because the borrowed wand was a high-performance dragon-headed magic wand.)
