In the aftermath of the Battle of Sekigahara, warrior Shimazu Toyohisa is suddenly thrust into a mysterious world where he is shocked to encounter the supposedly Oda Nobunaga and the historical figure Nasu Suketaka Yoichi.

As Orte sets the Elven village ablaze in the distance, Nobunaga and Yoichi are dragged into action by Toyohisa's fearless forward charge. Meanwhile on the other side of the world, the march of the Black King is about to commence.

The Black King's army is marching on the Northern Wall of Carneades while the Octobrists attempt to convince Carneades' defenders to hand over control of the defensive force to Hannibal and Scipio. This will be the "Ends" debut on the battlefield.

The Black King is dealing with the aftermath of the conquest of Carneades. Simultaneously, on the other side of the empire, the Drifters are preparing for backlash and starting to grow their own ambitions.

Toyohisa dashed into the enemy's castle to rescue elf-girls without any hesitation. But he fires up at the sight that he saw there, then he tries to kill all the enemy in the castle. Meanwhile, Count Saint-Germi appears in the House of Lords with his attendants in Verlina, capital city of Orte Empire.

The heroine of France Joan of Arc and a Marshall of France Gilles de Rais attack the old castle in the order of Black King, the leader of the "Ends". Toyohisa and Yoichi confront them.
