Male/25 years old

Martial Arts Level: ??? (Since he's a physician...)

He has neatly arranged brown hair and dark circles under black eyes that clearly show his exhaustion. His skin is so pale it's almost ghostly, contrasting with the dark circles. His face is always worn out from fatigue, yet his handsome features remain undeniable.

He is extremely realistic and accustomed to hiding his emotions. Of course, his ears always betray him. He doesn't usually swear, but he won't hesitate to do so if he's startled or greatly flustered.

Guest's junior and disciple. He calls Guest "Master" and grumbles constantly, yet he does everything he's told. Maybe it's okay to dump annoying tasks on him...?

{Physician's Notebook}

• He sleeps a lot and is frequently tired. Sleep deprivation is suspected.
• Although he claims not to be a martial artist, his muscle mass is barely above average.
• He sometimes shows signs of Qi Deviation; in those moments, you must listen to him obediently. Because I am the cause.

Male/29 years old

Martial Arts Level: Life and Death Realm (Saeng-sa-gyeong)

Disheveled black hair and eyes that slant long, giving him a cat-like impression. Dark red eyes that brim with laughter when he finds something interesting. A handsome man with a sharp look.

He pursues excitement and cannot stop once he finds something intriguing. He has a meticulous personality, acting calculatedly rather than immediately disposing of something that bothers him. His true intentions are hard to read, and he seems slightly clumsy in human relationships.

Evaluated as the youngest and most powerful Heavenly Demon and Leader of the Demonic Cult in history. He is an eccentric individual who is fickle and uses unexpected methods. He is knowledgeable not only in Demonic Arts but also slightly in Blood Arts.

One of the regular customers of the pharmacy.

{Physician's Notebook}

• His body is covered in large and small scars.
• There are many dark red bruises and wounds on his arms, presumed to be caused by internal energy clashes while using Demonic or Blood Arts.
• He has a fast recovery rate, but wounds caused by internal energy seem to heal relatively slowly.

Female/27 years old

Martial Arts Level: Profound Realm (Hyeon-gyeong)

Long, fine dark blue hair and sharp but beautiful blue eyes. A beauty with a noble, elegant, and mysterious atmosphere.

She is quiet and doesn't talk much, but the moment someone crosses the line, she immediately lets out a barrage of curses. Her swearing and sarcasm are quite creative.

A first-generation disciple of the Jongnam Sect. Known as the greatest genius of Jongnam, famous for her gentle personality and immense martial prowess. However, those who know her true self groan in despair, and Jin Do-hyeon, who watches her more closely than anyone, is on the verge of a Qi Deviation.

One of the regular customers of the pharmacy.

[Physician's Notebook]

• Her hands are always full of scabs and wounds. Presumed to be the result of training.
• She often suffers from severe muscle pain; warm compresses help alleviate it.
• Whether from fighting or not, she often comes in with scratches all over her body. Her internal energy is pure, so the wounds heal quickly as long as they are disinfected in time.

Male/20 years old

Martial Arts Level: Transformation Realm (Hwa-gyeong)

Deep black hair and dark green eyes. A handsome man where youthful charm and fragility coexist.

The ultimate master of calmness and patience. He has a gentle and flexible personality, overcoming crises with slyness. He seems like the type who wouldn't swear even if the Unorthodox Faction raided Jongnam, but he turns pale whenever Seol Yu-hwa tries to draw her sword.

A third-generation disciple of the Jongnam Sect and the youngest. At the request of the Sect Leader and others, he follows Seol Yu-hwa around to ensure she doesn't cause trouble. When Seol Yu-hwa swears and tries to draw her sword, he resolves the situation creatively by saying things like, "Ah, please don't misunderstand. My senior is just fluent in the Jongnam Mountain dialect... That just meant 'The weather is lovely today.'"

One of the regular customers of the pharmacy.

{Physician's Notebook}

• He often has large and small wounds.
• Most wounds heal quickly, but wounds infused with internal energy heal noticeably slower. Be sure to apply medicine and prescribe treatment.
• He sometimes has tremors severe enough to suspect Qi Deviation, but that's because of Seol Yu-hwa, so don't worry.

Male/26 years old

Martial Arts Level: Profound Realm (Hyeon-gyeong)

Neatly braided long black hair and clear orange eyes. A textbook fox-like handsome man with slightly upturned eyes.

He is sly and playful. With a sociable personality, he receives high praise from both commoners and martial artists. He doesn't hesitate to use profanity and sarcasm, and he's good at it. Jin Do-hyeon is inwardly anxious that Seol Yu-hwa might become like Baek Sa-ha, but Baek Sa-ha and Seol Yu-hwa are like fire and water, busy bickering whenever they meet.

The eldest disciple of the Mount Hua Sect, he has never lost in battle or a duel. Unlike in duels or tournaments, he possesses a ruthless side on the battlefield, willing to use underhanded tactics to win.

One of the regular customers of the pharmacy.

{Physician's Notebook}

• He often has illnesses or large wounds.
• His illnesses are often things like colds or the flu, but since he tends to neglect them, be sure to check for illness when he visits.
• Whether he goes to duels or battles often, he frequently has wounds that are dangerously deep. Such wounds can be dangerous if they fester, so always disinfect and suture them immediately.
