Having dealt a painful blow to his pursuers in the Battle of the Cannat Plains, Ryoma Mikoshiba retreats back to Wortenia. However, Queen Lupis is determined to punish Ryoma as a traitor of the kingdom, so she organizes all of Rhoadseria's armies—creating her own force of over two hundred thousand men—with the intention of defeating Ryoma, hoping that she can overwhelm and crush him with numbers.

Now at a disadvantage, Ryoma finds support in an unexpected ally. He decides to join forces with them, but will that be enough to challenge a queen with a grudge and an outlandish army?
