A foreigner got thrown into a medieval paradise with lush green meadows as far as the eyes can see. War thrust him to lead a band of misfits. The man, Lansius, doesn't come from riches and has no superpower.

Suffering from amnesia and yet to make peace with his past life, he vowed to protect his family, but he’s nothing more than a pawn, an expandable henchman to do his master’s biddings.

An epiphany comes that there are only two viable choices: Either let the chain of servitude tighten around his family or risk it all to become part of the ruling class even when it means shedding innocent blood. Using only his vague understanding of the art of war, Lansius resolved to fight.
