   Summary

   Three hundred years after the Calamity War, Mars is a world that feeds on forgotten children. From its slums, Tekkadan rises—first as disposable soldiers, then as something far more dangerous: a force that refuses to disappear.

   Led by Orga Itsuka and driven by Mikazuki Augus, Tekkadan claims Gundam Barbatos, a relic of brutal, forward-moving power. But buried alongside it lies another machine—Gundam Fenrir, an executioner and hunter built not to charge, but to pursue and end wars at their source.

   Its pilot, Ragnar Ravenson, does not seek command or glory. He endures. Where Mikazuki advances without hesitation, Ragnar waits, watches, and strikes only when escape is no longer possible.

   Together, two Gundams reshape Tekkadan’s destiny—one breaking the path ahead, the other ensuring nothing rises behind them. As Gjallarhorn closes in and the weight of power grows heavier, Tekkadan must decide what kind of future their strength will buy.

   Some fight to survive.

   Some fight to move forward.

   And some carry the burden of the ending.
