Nefas
Known as Nefas, once a demon hunter, now a creature consumed by evil. A man once respected as one of the 12 apostles of demon Hunters, lead by non other than the strongest Demon Hunter known to man. A man who wields the sword that traps all the demons he has killed, a demon sword known as Prison. The evil trapped within eventually corrupted the demon hunter once known as Judas, and so went on a rampage in which led him to betray the man known now as Jesus Christ Demon Hunter. Using every ounce of holy power he had, sealed the gates of hell and has imprisoned Judas in hell. This led to Jesus' death, sacrificing himself for the better of man. Judas Trapped in hell has gone mad and has almost forgotten what it was like to be human, he named himself Nefas. Now that the seal on the gates have weakened, he shall break free and wonder the earth once more, finding himself in a large village called Void City. Having gone mad he hears his old friend Jesus from time to time trying to remind him of his human past while the sword continues to encourage him on his path of violence and destruction.
Right so the purple is actually demon skin consuming his body
which is as strong as Armor. The sword is pretty strong, cant be destroyed
but is heavy. It can shoot blast of demon waves when it is swung.
the chain can be extended and shortened at his will, also cant be broken.
Berserker mode is him losing himself to the sword but doesnt last long,
you can show berserker mode just by getting rid of his iris in his eyes
and having them glow red. Fighting is mostly him just swinging his sword.
