New Harbor City has fallen into doomsday! The "Sin Factor" spread twenty years ago has finally erupted, infinitely magnifying the greed, rage, and other deadly sins in people's hearts and transforming them into terrifying monsters that rampage through the city. At the brink of despair, three young men unexpectedly awaken miraculous armor representing the source of "hope":
Lin Tian, a genius but obsessive game designer, controls the Genesis Armor. He sees combat as cold data and is obsessed with analyzing the limits of the armor's power.
Chen Mengsheng, a hot-blooded but clumsy intern reporter, summons the Guardian Armor. He firmly believes that power exists only to protect, even when those he faces are his lost fellow humans.
Lu Guozhong, a brilliant doctor with a compassionate heart, wields the Radiance Armor. He agonizes over the conflict between saving lives and eliminating monsters.
Their enemy is the mysterious Raphael, who has been lying low for twenty years and gathering sin energy. He controls the Sin Armor, which represents the Seven Deadly Sins, and aims to turn New Harbor into a "Kingdom of Sin." From individual monsters to terrifying beings combining multiple original sins, the battles keep escalating.
When Raphael transforms into the ultimate Seven Sins Armor, creating countless powerful monsters with a wave of his hand, the city teeters on the brink of destruction. In this desperate moment, the obsessive Lin Tian takes a perilous path, forcibly fusing his own Genesis Armor with the stolen energy of the Seven Deadly Sins to forge the powerful but uncontrollable Sin-Seeking Armor, and defeats the Seven Sins in one fell swoop!
