The Storyline

The Origin

After the devastation of two world wars, the Hidden Church was reorganized under its new elder, Albert, who established the supra-national agency GIA to investigate and contain supernatural phenomena independently.
Albert believed in using demons to fight demons and approved Project Seraphim, which aimed to create humans capable of wielding demonic abilities.
During an excavation of ancient ruins in the Qinling mountains, Qin Mo vanished for several months. When he returned, he claimed to have been trapped in another plane, where he witnessed the Fireseed, a world-shaping artifact that had long been pursued by The Hidden Church.
He also emerged with the anomalous ability to write reality into existence. Catherine convinced Albert that Qin Mo posed no direct threat, recruited him into Project Seraphim.
Under his involvement, multiple subjects were created, including Subject 0 (Elena) and Subject 13 (Moming).
For years afterward, the “demon” guiding Moming appeared in Elena’s form—though its true identity was unknown to him.
In 1999, Elina led Seraphim subjects to break containment, causing many losses and forcing the program to shut down. Qin Mo disappeared. Moming, the only stable survivor, was frozen.
In 2008, Qin Mo resurfaced and attempted to retrieve Moming. His attempt failed, and he was imprisoned in Niflheim, while Moming was sent to Manhattan to grow up under controlled observation.
Dark Stories Come True

Eighteen years later, Qin Mo escaped the prison. Shortly thereafter, the dark stories he had written inside prison became true.
Catherine recruited Moming to the GIA. They investigate manifestations across New York, Tokyo, and Hong Kong, uncovering Qin Mo’s attempt to revive the Seven Deadly Sins.
As Moming relied on his demonic abilities, their side effects made him extremely unstable.
GIA director Albert, assessing him as a high-risk anomaly, issued an execution order. Agent Victoria refused to obey the order, assassinated Albert, and escaped with Moming.
The resulting leadership vacuum allowed The Hidden Church to seize full control of GIA. Victoria was later killed by the GIA, and her death drove Moming into rebellion.
The Rebirth of Lilith

Seeking answers, Moming returned to the abandoned Seraphim facility. There he uncovered the truth of the 1999 incident and realized that the “Elena” guiding him was not the deceased Subject 0.
The entity revealed herself as Lilith.
By then, Moming had already traded away his soul to gain power, enabling Lilith to take complete control of his body.
Under her command, a massive ritual involving the sacrifice of millions was conducted, resulting in Lilith’s full resurrection.
Confronting Lilith, Catherine activated the demonic force bound to her own being—Jörmungandr, the World Serpent—and used the ancestral dagger once employed in an attempt to kill Promia. Through the combined power, she succeeded in destroying Lilith. Moming, however, was considered evil and burned on crosses by the hidden church.
Following additional clues in Qin Mo’s manuscripts, Catherine entered the Death World, a plane formed from unfinished narratives.
There she found Qin Mo, trapped within the system of stories he had written. He explained that after gaining the power to write reality, he became overwhelmed by an internal demonic presence, producing numerous dark narratives he could revise but never erase.
He asked Catherine to eliminate the remaining embodiments of the Seven Deadly Sins so the story could reach a controlled ending.
In the Death World, Qin Mo also located Moming’s displaced soul and returned it to Catherine.
Catherine then returned to the real world and sequentially defeated Jörmungandr (the demon bound within herself) and Michael, the entity that had been secretly controlling The Hidden Church.
With these final adversaries removed, Qin Mo’s dark narrative arc reached its intended conclusion.
The Lost Paradise

After the Seven Deadly Sins were destroyed, Qin Mo's story ends. Without warning, the world transitioned into the Lost Paradise.
Towers emerged simultaneously across every major city, suppressing human desire, malice, and all demonic influence. All wars and conflicts in the world have disappeared, and people live in peace and harmony.
Catherine suspected that all of this was Qin Mo's plan. She traveled to the original Qinling excavation site in search of answers.
In the collapsed ruin where Qin Mo had vanished years earlier, Catherine found his actual corpse. It turns out that the real Qin Mo was never able to leave that mountain.
This discovery exposed the truth: The figure who had led Project Seraphim, escaped Niflheim, written the dark manuscripts, and reshaped reality was Promia, the mythic bearer of the Fireseed.
During the Qinling incident, Promia had taken Qin Mo’s body and memories, allowing him to function as Qin Mo while pursuing his own objective: The construction of the Lost Paradise—a world without desire, evil, or demons.
To restore human autonomy, the remaining GIA forces entered the collective unconscious plane and reactivated suppressed emotions.
As the Towers began to fail, Promia issued a final warning:
Destroying the Lost Paradise would erase every character he had written—including Moming.
Moming accepted the consequence. Catherine confronted Promia and used Jörmungandr’s dagger—the same weapon that killed him in ancient myth—to end his power. When the Towers collapsed, the narrative structures maintaining his existence dissolved.
All characters in Promia's story disappeared, exactly as he promised.
Aftermath

With Promia's defeat, the world reverted to its prior state.
All story-dependent constructs vanished, including Moming.
Promia confessed a last truth to Catherine: as a demon inheriting human memory—just like her—his motives were shaped by Qin Mo’s genuine desire to create a better world.
Although the Lost Paradise failed, he preserved a fragment of his manuscripts—the section containing the characters he valued most.
Catherine was able to meet Moming again, restored from the last remaining piece of Promia’s written world.
