Having been promoted to a baron and given governance over the Wortenia Peninsula, Ryoma Mikoshiba and his companions build up their new land, which is gradually growing into a real domain. However, threats still abound within the territory, and the neighboring nobles are all conspiring against him. On top of that, other factions are vying for dominion over the western continent, and Ryoma is called on to help defend Xarooda against the O’ltormea Empire. Can Ryoma help stop the empire’s invasion, or will a conflict of this magnitude mean the fall of the young, upstart baron?
