High school student Mikoshiba Ryouma was summoned to a different world in the middle of a war. Sensing the malice from the one who summoned him (a summoner of the O’ltormea empire), he uses his martial arts to run away, killing important people of the empire during his escape. After the escape, he rescues two twin sisters from the hands of thieves. The sisters who can use magic, swear to serve him as subordinates. Thus, Ryouma begins his journey on the path of the supreme ruler.

The year is 407 AD and Rome is at the precipice. In the West, a usurper by the name of Flavius Claudius Constantinus has declared himself emperor. By doing this, he and his traitor legions have fractured the Western Roman Empire into two. At the same time, the north bleeds! Countless germans swarm across the borders of the Empire and pillage its lands in their ruthless raids. Alaric, King of the Goths, rises to a position of prominence and threatens the ancient capital of the dying Empire with his barbarian hordes. As if things weren't bad enough, rumors from the east state that a mysterious power rises within the fogs of war, threatening to drown the Empire in a river of blood.

As a response to these threats, the indolent emperor Honorius has given orders to his supreme commander Flavius Stilicho to reclaim the province of Gaul from the usurper. However, should he leave the heartland of the Empire undefended, undoubtedly Alaric would invade. Thus, under the threat of barbarians at the gates, Stilicho dispatches a young roman general by the name of Titus Claudius Marcellus to bring an end to the reign of the usurper. Will Rome fall to the tides of barbarians and traitors alike? Or can Marcellus restore a world collapsing around him? Find out in Heir of Aurelian!
