These armies are part of the Imperial Subjugation Army, led by the general Shushun Zaku Cannon. Inside the stronghold, Chouryou, along with Choubou Bolinoak Samaan, are panicking over the sheer force of the army outside. However, Choukaku Palace Athene is not afraid, and has a plan to counter them. The East Wing of the army is led by Sousou Gundam, and decides to attack without Zhu Jun's order. The West Wing is led by Sonken Zephyranthes, and he too decides to attack. The two wing armies attack, and Chouhi wants to join in the battle. However Ryuubi stops him, saying that something is amiss. Back at the Main camp, Shushun is enraged at the unannounced attack from the wing armies. The two wing armies soon realize that the Yellow Scarves defense is spread too wide, and the invasion seems too easy. The Chou brothers have escaped.
