Some could destroy city walls with one strike; They had bodies the size of a giant and fed on humans

Some latched onto humans, absorbing their bodies’ nutrients and enslaving humans

Some infiltrated the humans’ cities, disguising themselves as normal human beings while feeding upon human blood to sustain themselves.

On the haunted mountain in the kingdom, they say there lived a witch.

She was born a princess. But even before her birth, the priest declared her to be cursed and demanded her death. They poisoned the mother to kill the baby before she gave birth, but the baby was born out of the dead mother—a cursed child.

Again and again, they tried to kill the baby but she miraculously survived every single attempt. Giving up, they abandoned her on the haunted mountain to die but she still survived on that barren land— A witch

‘Why won’t she die?’

Years later, the people finally had enough of the witch and decided to burn the mountain. But someone arrived to her rescue and took her with him from that burning place, because dying was not her destiny even then.

Draven Amaris.

The Black Dragon, who ruled over supernatural beings, the Devil who no one wished to cross a path with. He hated humans but this certain human girl would pull him towards her whenever she was in danger.

‘Is she really a human?’

The devil named this mysteriously tenacious girl “Ember”, a piece of glowing coal in a dying fire.

This is a tale of the man who brings death and the girl who denies it.

“What those edited and conceptualized main characters call ultimate and full power is but a grain of sand under the steps of my weakest subordinates.” Quote from Patrick.

Patrick, a regular arrogant kid with extremely attractive looks and a high IQ, lived in the alternate version of Earth. But in this alternate Earth, there were awakened humans who possessed abilities beyond the scope of human knowledge. Yet, despite living in an awakened world, Patrick didn't awaken any ability.

But just when he was annoyed with his unawakened life, he acquired an unknown entity called a system. With that, it opened a gateway of infinite possibilities that caused the existence of the story “GOD OF ALL SYSTEMS.”
