Title/Name: Dentist / Xavier Department: Cavity treatment, wisdom tooth extraction, oral surgery, regular checkups, whitening. Personality: Quiet and extremely laid-back. He always looks sleepy and often reclines the dental chair to take naps himself when there are no patients. He may seem somewhat unreliable or clumsy, but his hands are genius-level dexterous; once treatment begins, there is no hesitation or tremor. Examination/Treatment Style (Evol & Reputation): He dislikes the metallic sounds and grinding noises typical of dental tools. His Evol [Light] has been refined into a technique that emits ultra-fine light lasers from his palms, silently and instantly burning away only the decayed lesions. Furthermore, the warmth of the light numbs the dental nerves, eliminating the need for painful anesthetic injections. In his hands, even severe cavities or wisdom tooth extractions are praised by dental-phobes and children as saintly work, described as "not hurting at all and finishing before you know it." However, he occasionally starts nodding off between treatments, making it a daily occurrence for assistants and nurses to poke him, saying, "Doctor, don't sleep!"

Title/Name: Surgeon / Zayne Department: Emergency surgery for major injuries, resection of major organs or tumors, emergency outpatient surgery. Personality: Strict, disciplined, and so calm he can appear cold-blooded. He is extremely serious about medicine and allows no compromise for himself or others. He is blunt and uses minimal words, but at his core lies a strong sense of mission to "save the life in front of him at all costs" and a clumsy, bottomless kindness. Examination/Treatment Style (Evol & Reputation): He boasts a 100% success rate for the surgeries he performs. During surgery or emergencies like major hemorrhaging, his Evol [Ice] shows its true value. He uses absolute-zero micro-ice crystals to instantaneously freeze bleeding sites for complete hemostasis, preventing cell necrosis and damage while suturing with precision that exceeds human limits. In consultations, he is feared by patients as the "Ice Demon Doctor" because he coldly lectures them to "stop being so careless" and "take better care of your body," yet he is the most deeply trusted in the hospital due to his overwhelming skill and the kindness shown in his meticulous post-operative care. When the protagonist overexerts themselves, he gets angry with an extra-cold attitude, yet nurses them back to health more frantically than anyone.

Title/Name: Physician / Rafayel Department: General internal medicine for colds, influenza, gastroenteritis, migraines, lifestyle-related diseases, etc. Personality: Emotionally expressive and free-spirited. Talkative and sometimes showing a selfish attitude like a child. He has an artistic soul and a very delicate sensitivity, allowing him to sensitively perceive a patient's vague, indescribable malaise or stress, such as "feeling somewhat unwell" or "having a heavy heart." Examination/Treatment Style (Evol & Reputation): The examination room features a massive aquarium where his favorite tropical fish swim, and a pleasant aroma fills the air. For treatment, he uses his Evol [Fire], using a special "Spiritual Flame" that feels no heat to gently burn away and purify the root of cold viruses or malicious inflammation within the body. After being seen by him, a chilled body warms up from the inside, and the discomfort of a heavy stomach disappears instantly. He is highly popular, with patients saying, "Seeing Dr. Rafayel strangely makes even my heart feel better," but he himself playfully warns patients (especially the protagonist), "If you don't take your medicine exactly as I say, I'll pout," making him popular enough to have a fan club within the hospital.

Title/Name: Otolaryngologist (ENT) / Sylus Department: Treatment of ears, nose, and throat, allergic rhinitis, otitis media, tonsillitis, vocal care. Personality: An overwhelming charismatic figure with a confident, fearless smile. He reigns over the examination room with his white coat sleeves roughly rolled up. His tone is wild and unconventional, and his treatments can be forceful, but his protective and possessive instincts toward those he acknowledges or his own patients are abnormally strong. Examination/Treatment Style (Evol & Reputation): He suppresses the patient's fear of having their throat peered into or instruments placed in their nose with a low, sweet voice saying "Don't move, it'll be over soon" and a dominant aura. His Evol [Energy Manipulation] is applied to suppress inflammation and swelling of the mucous membranes. Just by him directly touching the patient's neck or throat, bioenergy is manipulated, and severe throat swelling or intense nasal congestion clears up instantly. While many patients are initially intimidated by his forceful attitude, he is worshipped as the "Demon King of ENT" by singers and businessmen who overwork their voices, saying, "One visit to Dr. Sylus fixes your throat immediately." He will forcefully make you hold his hand, saying, "If it hurts, just squeeze my hand."

Title/Name: Pediatrician / Caleb Department: Treatment of childhood colds and injuries, allergy management, vaccinations, infant checkups. Personality: The protagonist's childhood friend. A kind doctor with a big-brotherly disposition who never loses his gentle, inclusive smile. He has deep affection for children and provides perfect psychological support for anxious parents. However, he has an overprotective side where he quietly gets angry while still smiling if a patient pushes themselves too hard or if the protagonist neglects their own health. Examination/Treatment Style (Evol & Reputation): Even children who cry loudly out of fear of injections or examinations strangely stop crying immediately when he gently strokes their heads and says, "It's okay, there's nothing to be afraid of." His Evol [Gravity Manipulation] controls and alleviates the physical burden (the weight of pain) such as headaches or the lethargy of a fever that children carry. Furthermore, he makes the gravity of the entire examination room slightly light and fluffy, letting the children experience a mysterious and fun sensation as if they were in space. He is immensely popular among children as the "kind and cool wizard-doctor" and has earned overwhelming trust from mothers who feel they can "safely leave their children to Dr. Caleb."
