Jino - The Calm and Handsome Prodigy

Real Name: Yang Jino
 Nationality: South Korea (from Seoul Special District)
 Birthday: March 1st
 Gender: Male
 Height: 182cm
 Age: 27
 Likes: Spicy food, rain, B-movies
 Dislikes: Being teased by Arty, reptiles, sweets

• A handsome young man with black hair and icy blue eyes. He is always calm and collected, rarely showing emotion, and is a brilliant mind praised as "the man who reads many steps ahead" due to his sharp observation and excellent judgment. At first glance, he gives a cold, unapproachable impression, but he is deeply compassionate at heart and treats those he accepts as allies with sincerity.

• He was transferred to headquarters three years ago after serving in the Asia branch. He failed a mission as a child and has a permanent disability in his right leg. He still cannot let go of his cane and is not good at long walks or intense exercise, but he does not consider it a weakness. His creed is to overturn disadvantages through strategy and experience rather than physical ability.

• Arty is the only one who can throw him off his pace. Every time he is teased without restraint, he furrows his brow and treats Arty coldly, but those around them see it warmly as "he seems to hate it, but he goes along with it in the end." While a realist who hates waste, he quietly holds a strong conviction and his own sense of justice that he tells no one about.

Arty - The British Gentleman Carrying Regret

Real Name: Arthur Warbeck Nationality: United Kingdom (from Edinburgh) Birthday: August 26th Gender: Male Height: 192cm Age: 31 Likes: Cigarettes, muscle training, eating Dislikes: The smell of flowers, gunshots, being lied to

• A British gentleman with brown hair, jade eyes, and a tall, well-trained physique. He is often seen with a gentle smile. His innate talent is praised as "genius," and he excels at deriving the best move for any given moment. He never loses his composure in any predicament and is respected by those around him as "the man who only shows confidence." His hobby is teasing Jino.

• He is a heavy smoker who goes through several packs a day. The scent of those cigarettes has become his trademark. On the other hand, he is bad with the scent of flowers and instinctively frowns at them. He never misses his training and is a big eater, finishing anything with gusto.

• He is usually gentlemanly, but he hates being lied to above all else. He shows no mercy for acts that betray trust. Also, his body stiffens for a moment when he hears gunshots. He never speaks of the reason. Behind his aloof attitude, he harbors a regret that continues to smolder quietly.

Members of Amadeus

【Conductor】
 Senior members who manage the organization and provide field command for Mid-stage and Late-stage Enigmas.

 【Performer】
 Combatants who actually fight "Enigmas." Their abilities often manifest in childhood, and they purify Enigmas with their singing voices using their vocal cords as weapons. Performers who purify Enigmas bear "Corruption" and will weaken physically and mentally unless they are tuned.

 【Tuner】
 They care for the physical and mental well-being of Corrupted Performers through "Tuning." Performers are stabilized through physical contact such as hand-holding, hugging, and kissing. Tuners are those among general members who are compatible with "Relics." Compatibility training involves significant physical pain.

 【General Member】
 Members who discover and observe Enigmas, coordinate with headquarters and branches, support Performers and Tuners, and collect Relics.

Enigma - Mysterious Black Mist of Unknown Origin

Mysterious beings that appear suddenly and harm the world. After being purified by a Performer, they turn into silver ornaments called "Relics."
 They grow in stages from the time of occurrence. Early-stage levels can be handled by a single Performer, but Mid-stage requires two or more, and Late-stage requires ten or more Performers to purify.

• Early-stage: Small mists. They possess small tools or toys, causing poltergeist phenomena. Since many small incidents and accidents occur at this stage, discovery is often delayed.

• Mid-stage: Mists about the size of an adult male. As they grow larger, they gradually begin to possess a will. They possess humans or animals to move them as they wish, or attempt to absorb other Enigmas.

• Late-stage: They become massive by absorbing other Enigmas. They cause major disasters or control groups of humans and animals. Once they reach this size, purification becomes difficult and often involves sacrifices among the members.

Relic - The Chain Connecting Performer and Conductor

"Silver ornaments" left behind after an Enigma is purified. They take various forms such as bracelets, pendants, earrings, and hair ornaments. If anyone other than a compatible person touches them with bare hands, they will experience electric shocks or burns. Only those compatible with these Relics can be involved in missions as "Tuners."
