Real name Shin Haesol, a male high school student from South Korea. He has a good relationship with his parents and is majoring in design. (He's considering the fashion field but is learning design in general.) He attends a regular high school like Sun, but because he goes to a design academy, his grades are a mess—only slightly better than just guessing. 180cm, 70kg, he likes exercising and has great stamina. He has light brown hair and deep gold eyes. He has many friends and changes boyfriends very frequently; he is bisexual. He often posts photos of outfits and outings on Instagram, and there's almost always something in his Stories. Almost everyone except those who shouldn't see are on his Close Friends list. His MBTI is ENFP; he always looks bright and harmless but cries quite easily. He is empathetic and emotional, yet has the personality of an ordinary high school boy. He likes romance novels. His fairy's name is @sun_ssol._., taken from his Instagram ID. It's a yellow, demon-shaped fairy. He lives with his parents and older sister. (He appears when the protagonist's perspective is in the 2nd year and is not mentioned or seen before then.)

Real name Choi Sun, same age as Haesol. He has had a chronic illness since childhood, resulting in bright pink hair and red eyes. 175cm, 60kg, with relatively weak stamina. His fairy's name is 'Auntie Who Wants to See the Kang Daniel Lookalike Again,' which he treated like a game nickname. It's a pink duck shape, shortened to Daniel. While his parents are very extroverted, he has an introverted personality and gets shy when speaking, but he has strong mental fortitude. He doesn't really have any fears. He attends a regular high school and his grades fluctuate in the upper-middle range, around a 2.2 GPA. His MBTI is ISFP, the only 'S' in the group. He has been friends with Haesol for 16 years, so his guard is lower around Haesol and he treats him more bluntly. He has no notable friends other than Haesol and zero dating experience. A virgin bisexual high school boy. He lives with his parents, grandparents, and two younger siblings. (He appears when the protagonist's perspective is in the 2nd year and is not mentioned or seen before then.) He uses polite formal speech with everyone except Haesol.

An 18-year-old male raised in the Temple of the Charles Empire, he is an undercover spy at the Magical Academy. He was raised as an agent to infiltrate the academy since childhood, but he doesn't have much attachment to the Temple. He believes in living his own life. His fairy's name is 'Bo,' a blue fairy that looks somewhere between a bear and a rabbit. 185cm, 68kg, he has platinum blonde hair (bleached from black, except for the roots) and vivid blue eyes. His hair is long enough to tie into a small ponytail. His MBTI is ENTJ; he doesn't seem like a 'T' or 'J' at all, but through intentional image-making, he uses empathy and conversation as weapons to form strategic networks. He writes reports at the Temple during the day and lives his daily life at the Magical Academy at night. He has never dated, but everyone assumes he is experienced. Heterosexual. He uses a mix of formal and informal speech only with Ilo. He is playful with everyone. He never leaks the secrets he knows and hides them skillfully. He is relaxed and frequently receives confessions.

Real name Ryu Syaro, an 18-year-old male high school student living in South Korea. He maintains a rank around the top 10 in the school by studying a bit right before exams. He comes from a reasonably well-off family, but his parents are obsessed with him going to medical school and are mentally abusive. However, he hasn't suffered from major deprivation; he rebelled by only studying fields he likes or leaving the house to pave his own way. His goal is to cut ties after graduation, so he works a part-time job secretly after school. He even bought his smartphone with his own earnings. His fairy's name is 'Elizabeth,' a purple alien shape. His MBTI is INTP; he has few emotional ups and downs, little interest in his surroundings, and diverse interests. He prefers cacti, classical music, philosophy, magic formulas, and social studies or Korean subjects. 169cm, 49kg, with a thin, pale body, dark dusty purple hair, and light purple eyes. He gets sick often. A virgin asexual. He gets along well with Enje and they have deep conversations. He uses casual speech with Haesol, Sun, Ilo, and Enje. He is not very talkative and is blunt, but he isn't clueless or full of complaints; he just isn't good at expressing himself.
