There are Humans. There are Elves. There are Dwarves. There are Orcs. And then there are Demons, and the Demon King.

In a world where warriors wield elemental fury, assassins bend shadows, and mages rewrite the laws of reality with a thought… one boy awakens the weakest and funniest ability of all.

[Muscle Genesis]… the power to grow and control muscle.

The f*ck? No sword aura, no magic affinity, no flashy technique, just raw, brutal power.

Born in the wild slums of Arcanum Nexus, orphaned, starving, and forgotten by the system, Kairo Vale has one goal: survive long enough to rise above it all. 

When his chance finally comes in the form of the prestigious Nexus Academy Entrance Tournament, the world expects him to fail, just another Unranked slum bastard with a useless ability.

But the thing about muscles is that… they grow.

And so does his pain tolerance, and his strength, and his will to endure.

Thrown into trials designed to break him, teamed with nobles who want him gone, and hunted by powers that fear what he might become, Kairo fights back the only way he knows how: one rep, one punch, one brutal threshold at a time.

Because in this world, power is everything.

And he’s going to build his from the ground up.

If they won’t give him a place in their world, he’ll carve one with his fists.

The world is one big planet called Scrontum. In planet Scrontum, the world is a giant body of water with 3 main big islands (continents): the Southern Continent, the Northern Continent, and the Eastern Continent. 5 Civilizations call planet Scrontum home: Demon, Elf, Orc, Dwarf, and Humans.


The Southern Continent has the biggest mass of land, and is where 3 of the Civilizations live: Demon, Orc, and Humans. The Eastern Continent is Home to the Elves, and the Northern Continent is Home to the Dwarves.


The Human domain has many cities, but they have a central neutral city, Arcanum Nexus, a free city where all factions gather for tournaments, trade, and politics, and also home to the most prestigious human Academy, Nexus Academy.


At awakening, each individual receives one or more Special Abilities, influenced by genetics, fate, and environment. These are categorized as:


*Combat Types: Weapon Mastery, Elemental Control, Beast Summoning, etc.


*Support Types: Buffs, Healing, Strategic.


*Hybrid Types: Bloodline arts, Shadowcraft, Cursed Skills, etc.


*Mutants/Deviants: Extremely rare abilities that don't fit the system.


Individuals are ranked by a combination of Combat Potential, Ability Grade, and Mana Core Development.


*F, E, D, C, B, A, S, SS, SSS (Legendary/Transcendent)


*Common, Rare, Epic, Mythic, Unique, God-tier


[Note: Most Awakened start with multiple low rank, multi-synergizing abilities. Our MC? Only one ability.]


An interface that has always been there from the inception of time alongside mana. It grants Awakened easy access to their powers and the ability to interact with the magical world.
