The Ai Army is the army led by Rou Ai, also known as the Rebel Army who wants to take over Kanyou. The Ai army is comprised of of three different armies. 10.000 men are under Han O Ki, 10.000 men are from the lands of Juuteki and are being led by Duke of Juuteki and 10.000 were recruited from various cities. In total they are a 30.000 strong army.
The Queen Mother and Rou Ai where being manipulated and blackmailed into attacking Kanyou. With the thought of "kill or be killed", The Queen Mother suggested that the best time to attack Kanyou would be at Ei Sei Coming of Age Ceremony. She used the fake royal seal she still had from the Sei Kyou Rebellion. Which allowed the rebel army to recruit 10.000 men from various cities they passed by. Initially they refused to fight for the rebel army after they knew they were attacking their allies, but they had no other choice in the matter. Once the first attack was over, they knew that there is no turning back now. Its kill or be killed.
The rebel army also tried to use the fake seal to get to Kanyou, but failed midway and were attacked by 3000 men guarding Kankoku Pass. However due to their overwhelming numbers they defeated the 3000 men army. 1000 men surrendered, but were executed never the less. When heading to Kanyou, they got wind of an incoming 10.000 men army at which they send Duke of Juuteki and his army to intercept.
The Duke of Juuteki fought against 1000 members of the Hi Shin Unit and 10.000 men of the people of Sai. The latter was an army hidden by Ei Sei in order to counter Ryo Fui and anyone else who wants to stop the Coming of Age Ceremony. The Duke of Juuteki tried to prevent the enemy from landing at shore, but Shin with the tactical aid of Ka Ryo Ten, they managed to get a foothold at which Duke of Juuteki had no choice but to retreat, leaving 3000 men behind.
They started sieging Kanyou as they then managed to get inside with aid from Ryo Fui's men inside Kanyou.
