[Your shadow is alive.][Feed your shadow, devour souls, level up, gain skills, complete quests, and grow stronger.][Do you wish to view your current stats?]In the magical world of Aetherus, Damon Grey is the weakest student at Aether Academy, relentlessly bullied and ridiculed for his lack of power and defiant personality. Yet, he endures the torment, clinging to his scholarship—the only thing providing him with the funds to keep his sick sister alive.After a brutal attack leaves him near death, Damon encounters a dark viscous entity in the forest that fuses with his shadow, awakening the Living Shadow System. This strange power grants him unimaginable abilities but comes with a grim cost—a relentless hunger for souls and flesh to feed his shadow.Now, with his shadow alive and insatiable, Damon faces a terrible choice: feed it to grow stronger or starve it and die with it.In a world ruled by ruthless nobles, deadly monsters, and power-hungry demons, Damon must decide if his newfound power is a curse or the only way to survive. With the Living Shadow System, his fate is clear: devour or be devoured.

A hero must be compassionate, selfless and courageous.But that isn't all. Because a hero must also be powerful.In this world, power is everything. Strength decides who gets to save lives and who's left with community service. That’s why I was nothing — a rank 50 E-Class reject, skating through the streets, saving what little I could while the real heroes battled gods and monsters.Then one day, I died. Almost.Dragged into the abyss, I was given a second chance: the Forever Core. An armor that evolves. A system that never stops adapting. Every battle, every hit, every mistake, I come back stronger.Now, the monsters that once crushed me can’t kill me the same way twice.I must adapt. Evolve. I must grow stronger and fight harder. Because humanity is worth fighting for.Even if I have to burn every villain alive to prove 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.”
