Hellborn Exorcist: Zero

In the neon-drenched city of Noxviel, demons lurk beneath humanity's feet while the holy Exorcist Order keeps the truth buried. Seventeen-year-old Ren Kael wants nothing to do with Heaven or Hell - until a demonic invasion destroys his district and leaves him dying in the ruins.
That's when he meets Zero.
A chained six-winged being erased from history. The first Hellborn Exorcist. A monster created by both angels and demons.
In exchange for his life, Ren becomes Zero's new vessel.
Now hunted by Heaven, feared by Hell, and slowly losing himself to the ancient power inside him, Ren is dragged into a hidden war where angels lie, demons bleed, and humanity is caught in the middle.
As the city descends into chaos and a forgotten apocalypse begins to awaken, Ren discovers the terrifying truth:
The greatest threat to the world may not be Hell...
But Heaven itself.
