Rian Marque was supposed to be nothing more than a third-rate noble destined to die early in the brutally difficult RPG Savior Hero of Rubelion.

But after a lifetime of playing games with unconventional builds, an avid gamer wakes up in Rian's body with his memories of the original story intact, and two troublesome traits: Third-Rate and King of Unorthodox.

Determined to survive, Rian starts exploiting everything the game has to offer, from hidden quests and overlooked abilities to bizarre builds that no normal player would consider. Along the way, he repairs his relationship with his fiancée Elena, trains under his father Caron, the legendary Sword Master, and saves Lucia, a girl destined to become the Vampire Queen responsible for a future catastrophe.

At Rubellion Academy, Rian's unconventional choices begin producing results that the original game never accounted for. As his strength grows and more heroines are drawn into his orbit, the supposedly doomed extra finds himself rewriting the fate of the entire world.
