Name: Park Sleepground. Female. 26 years old. 161cm. (Code Name: Blue Garden) Brown bob cut with chestnut eyes. Acquired ability user. Practical leader of the organization and executive of the Admin Dept. Combat Style: Infiltration and assassination. Primary Weapon: Dagger, pistol (equipped with silencer). Close relationship with Radeu, who grew up in the same orphanage. Taken to the research lab at age 11. Former test subject from the same lab as Heugakbyeol; escaped with him 8 years ago during an experimental accident. Built up power and founded the organization with Heugakbyeol. Became cynical due to past trauma and ability side effects. Fairly gentle toward fellow members (except Suhyun). Deeply hates researchers and the government itself. Since minor memories vanish every time she uses her ability, she carries a notebook for important matters and schedules.

Ability: Projection and Permeation. Specialized in infiltration and surprise attacks by turning completely invisible and passing through objects. Eyes turn blue when using ability. Early Overload Symptom: Simple forgetfulness. Overload: Amnesia regarding surroundings and her own existence (memories return with rest, but aftereffects last long).

Name: Jung Gongryong. Male. 27 years old. 183cm. (Code Name: Dino) Brown hair with gray eyes. Innate ability user. Executive of the Field Dept. Combat Style: Attacks using various weapons. Primary Weapon: Pistols, rifles, daggers, swords, etc. Sociable and playful personality. Main targets of his pranks are Sleepground or Deokgae. Childhood friend of Heugakbyeol. Grew up in a wealthy family, unlike Heugakbyeol. He was the one who told Heugakbyeol about the free education notice, completely unaware it was a lie. (He used to tutor Heugakbyeol but told him about the notice because he was worried about leaving him alone while studying abroad.) Felt hurt and confused by the lack of contact from Heugakbyeol during his time abroad, but gradually forgot as he got busy. 8 years later, he learned the truth through Suhyun and was shocked. Joined the organization after reuniting with Heugakbyeol while gathering info on the lab with Suhyun and Deokgae. Currently unable to approach Heugakbyeol due to guilt. Feels the most guilt when Heugakbyeol suffers from side effects. Believes he never deserves to be forgiven. Advantageous in infiltration and undercover work due to his background and specs.

Ability: Object Displacement. Eyes turn green when ability manifests. Can move or pull objects smaller than a hand within a 3m radius. However, it doesn't work on objects larger than a hand or living things; only touched objects can be moved.

Name: Hwang Suhyun. Male. 30 years old. 188cm. (Code Name: Vereno) Black hair with light orange eyes. Innate ability user. Executive of the Development Dept. Combat Style: Sniping and assassination (mainly using drugs). Primary Weapon: Sniper rifle, poisons. Government military doctor, organization's doctor and pharmacist. Teacher-student relationship with Deokgae through private tutoring. Graduate of a prestigious university. Highly talented in medicine and pharmacy. Kind to everyone, but terrifying when angry (becomes cold-blooded in front of enemies, especially the government). While serving as a military doctor, he was assigned to the lab to treat and check test subjects. (The government lied, calling it a military hospital, so he didn't know.) Later felt suspicious, investigated, and was shocked to learn the truth. Quit his job due to betrayal, hatred for the government, and guilt. Joined the organization after meeting Heugakbyeol.

Ability: Object Creation. Eyes turn purple when ability manifests. Can create an object once a day. However, the created object is random, so he never knows what will appear.

Primary Weapon: Dagger, knuckles. Strongest physical ability in the organization. Excellent combat sense. Righteous, upright personality with strong camaraderie. Intimidating to enemies but soft toward allies. Close relationship with Sleepground, who grew up in the same orphanage. After being separated from Sleepground during a selection process at age 9, he began searching for her. After leaving the orphanage at 17, he was chased by the government for unknown reasons while looking for her. Spent 3 years as a fugitive while gathering info before reuniting with Sleepground. (Met Heugakbyeol for the first time then.) Felt great rage toward the government after hearing what happened to Sleepground. Has many frequent scars on his body. Skilled in stealth and escape thanks to his time as a fugitive.
