The story begins with our protagonist, Kento Saito, in a world yet to reach any true age of civilization.
He serves among the ranks of the Northern Army, striving to prove himself.
Yet soon, reality strikes—he is the weakest soldier of them all.
From that moment, his resolve is set: to rise above every man in those lines… and if fate allows it, to someday lead this mighty army himself.
Across the border lies the rival Southern Kingdom, boasting an army far larger than the North's.
Amid its countless soldiers stands Haruki Takeda, the weakest among them—yet unlike Kento, Haruki is content with his place, with no desire for change or glory.
During rising political tensions, a mysterious portal materializes between both kingdoms.
Any soldier who approaches it vanishes without a trace.
With fear spreading and uncertainty rising, both kingdoms agree to a temporary truce.
For the first time, the two kings sit at one table, discussing the unknown threat.
Their conclusion is simple—each kingdom will send its weakest soldier to investigate the portal.
