On the third day, of the Simultaneous Battle Plan, Kyuu Kou pointed out to Kan Jou that an all out brawl wasn't their forte. Shou Taku agreed with him. Kan Jou told them to quit complaining, because that was the Gyoku Hou's way of doing things. Kyuu Kou then asked if he meant letting themselves take it easy at the back?
Kyuu Kou seems to be an adept mace wielder.
