Saiga Noburu was never meant to become a Sentai. He had no Astral Core, no power, and no future in the battlefield. Yet when the ruthless General Dragon Lord annihilated an entire Sentai squad, Noburu somehow survived—and the world mistakenly believed he defeated the monster.

Now the powerless Noburu is forced to act like a hero he never was.

With only a black armor left behind by his late father, he struggles to keep the lie from collapsing. But when he joins forces with Natsumi Kanzaki, a sharp magi-tech researcher, and Yumesaki Chisa, a childhood friend who refuses to lose hope, Noburu uncovers something terrifying:

The monsters attacking humanity may not be invaders…
They might be creations of their own government.

Trapped between a fabricated legend and a truth too dangerous to reveal, Noburu must decide:
Will he keep living as a fake Sentai—
or rise as a real hero born from a lie?
