He also led a surprise attack again the Hi Shin Unit beside Batei the right-hand man of Kisui. Ryuu Tou later on the day got injured by Kyou Kai, which led the Hi Shin Unit to push back his army. However, he made plan revolving the river, which put the Hi Shin Unit in a tight situation because they couldn’t push closer to the central hill. But by the combined effort of Ka Ryo Ten and En, they are able to push back the Ryuu Tou army.
When the Hi Shin Unit led by Shin trying to surprise on Kei Sha, who just got out of trap made Kanki, Ryuu Tou mistook the Hi Shin Unit for being messengers delivering a report to Kei Sha's HQ.

He was killed by Kyou Kai of the Hi Shin Unit.
