The F-Rank Who Challenged Heaven

"When even the lowest dares to rise, the heavens themselves tremble."
In a world reborn by the Heavenfall Pulse, power defines worth.
Guilds rule the cities, adventurers climb the ranks from F to Diamond-S, and those at the bottom are treated as disposable tools.
But when a young dragon-kin named Marshall Draganis - mocked as an F-rank scavenger - awakens two ancient forces within him, everything changes. Guided by the unseen Crimson Flame and the radiant Melody, Marshall begins to shatter the limits of power itself.
What starts as a fight for survival becomes a rebellion against the hierarchy of gods and men alike.
As monsters rise, guilds turn to war, and the heavens themselves begin to stir, one outcast will forge a path no rank can contain.
He will become the spark that defies destiny.
He will become the F-Rank who challenged heaven.
