Jeoff Ernstmann (angel engine)

After capturing the angel, Ernstmann began a series of experiments, during which he uncovered several facts. First, he discovered that the energy drained from the angel was sufficient to sustain all of humanity for several millennia. It was later discovered that the angel responded to the name Uriel. Furthermore, Ernstmann noted that the angel's intelligence exceeded existing human methods of assessment, yet the creature was not particularly forthcoming. In response to concerns about the angel's release, Jeff claimed that it was capable of escape. The most important discovery was that the angel's energy was capable of resurrecting people, healing the most severe wounds while causing the angel excruciating pain. The doctor calls this invention a miracle machine.
The possibilities of angelic energy are truly limitless. It is known that, thanks to it alone, humanity was able to restore the planet's devastated ecosystem and make it habitable once again. Jeff Ernstmann noted that angelic energy is so powerful that it could literally power the entire population of Earth. He also demonstrated that the power of the angelic drive can resurrect a person, as demonstrated by one of the recently deceased project participants. Using Uriel's energy, Jeff was able to create the Angel Corps—an entire race of artificial beings who would serve him, presumably in place of the Forgotten Ones, who cannot be presented to the public due to their deformity and aggressiveness.

A true embodiment of kindness, mercy, and love: he was the one who responded to humanity's call and came to its aid, saving them. His virtue and philanthropy are so profound that he succumbs to Doctor Ernstmann's deception and ends up locked in the Angel Engine's cage. However, despite the cruel treatment he receives from mortals, Uriel remains steadfast in his attitude toward humanity and continues to try to help them, warning them of how close this world is to destruction.
Uriel is initially introduced as a handsome young man with blond hair and wide white wings. He usually wears a white robe, similar to a monk's habit. In terms of height, Uriel is clearly larger than other people: he towers over Dr. Ernstmann by two heads, and is presumably around 220 cm.
After being imprisoned in the engine and subjected to constant torture, Uriel's visual image began to distort and become increasingly monstrous. His skin turned black, parts of his body decayed, his face now resembled an iron mask, and his wings had completely fallen off.
But for all his virtue, Uriel cannot be called naive: he understood perfectly well that humans are greedy and cruel, and therefore promised a generous reward to anyone who saves him. Like other angels of God, Uriel reveres his Creator and advises calling upon His name to protect oneself from Lucifer's will. The archangel cares for all people and is concerned for their future. The only one Uriel truly hates is Satan. Understanding that he is the one behind sin as a phenomenon, Uriel views people merely as victims deceived by him.

A charismatic and brilliant, yet morally corrupt scientist. He headed the Angel Engine Initiative, a daring project aimed at saving a destitute world. At its core was a sacrilegious act: the usurpation of the divine power of the imprisoned Angel Uriel. The energy of the celestial prisoner was harnessed to create artificial "miracles," fueling this man-made sacrilege. In reality, the doctor served and continues to serve Satan himself, having entered into a contract with the Hellish Prince Dantalion, exchanging his soul for the forbidden knowledge of creating an angelic engine.
The citadel of this dark genius was the Second Tower of Babel—a gigantic structure rising in the middle of the Negev Desert in Israel. Behind its impenetrable walls, a swarm of ants bustled with life: more than two hundred thousand souls toiled in the name of "the bright future of humanity." They forged the cutting edge of technological progress, unaware of what was happening in the depths of the subterranean world. For beyond its developments, the Tower concealed dungeons where cruel experiments were conducted—not only on the suffering angel, but also on others like themselves, doomed to become test subjects in the name of a dubious salvation.
