Secret of the Massir System

⚠️ A NOTE ON THE "AI-ASSISTED" TAG: Every single aspect of this story—the plot, the worldbuilding, the characters, and the fights—is 100% created by me, a human author. However, English is not my native language. I write the original draft in my native language and use AI strictly as a translation and grammar-polishing tool to make the text readable for you. No AI is used to generate the story itself. Thank you for giving it a chance!


Humanity was saved from the brink of self-destruction—only to be drafted into a cosmic war.

Rescued by the enigmatic alien race known as the Rowlids, humanity now survives across the five specialized planets of the Massir System. On the planet Ryss, the Order of the Sword reigns supreme. There is no magic here. There is only grueling physical conditioning, the ruthless physics of combat, and Senshi—a potent bioenergy channeled into blades forged of Orel metal through hilt receptors known as Dobas.

Hiro is a nobody, an orphan from the docks. But during his entrance exam, he unleashes an anomaly: a Senshi surge so massive it ignites three Dobas at once. A colossal, unheard-of feat for his age.

Drafted into the prestigious Green School of Seirin, Hiro must master the "Way of the Leaf" alongside his new comrades, Kai and Mike, to tame his overwhelming energy. But his gift is a dangerous omen. Twelve years ago, the only other student to possess such monstrous Senshi—a prodigy named Ren—went mad and attempted to assassinate the Viceroy of the planet.

Now, the fragile political balance of the Massir System is collapsing.

To survive the impending interplanetary slaughter, Hiro must forge his body into an unbreakable vessel, unmask a traitor within the Order, and uncover the dark, hidden truth behind the Massir System itself.
