Chou-un Joins! - S1.E11

Back at the Alliance campsite, Kousonsan and the sworn brothers hear the news of Sonken Zephyranthes' death, and how the Son army, now under Sonsaku, is still giving chase after Toutaku. The four decide to join up with the Son army to back them up. At the main gate to Rakuyou, the four are stopped by Chou-un Gundam, an officer under Enshou. Enshou has barred anyone from supporting the Son army's chase. Angered by this, Ryuubi draws his sword, to which Chou-un draws his spear. They both discuss how a soldier should follow a commander's orders and how one should always support their allies. Kousonsan steps in and agrees with Ryuubi's point of supporting one's allies. At this point, Chou-un succumbs, but he will personally escort them.
