Yam Koo is a fisherman and the sworn brother of Tai Ho. Unlike Tai Ho, Yam Koo tended to be more logical and didn't live his life purely by chance, calling Tai Ho's whims "Big Brother's madness". When Tai Ho and Yam Koo encountered Tir McDohl, Tai Ho told Tir that he and Yam Koo would only escort him to Toran Castle if Tir was willing to make as risky a bet as Yam Koo and Tai Ho would have to: by betting all their money. When Tir McDohl won, Tai Ho told Yam Koo to prepare the boat. Yam Koo agreed to go along, and the two escorted Tir McDohl and his party to Toran Castle.

As Tai Ho left with Tir McDohl to enter Toran Castle, Yam Koo told Tai Ho to be careful. Yam Koo stayed behind, waiting at the dock for Tai Ho and Tir McDohl's safe return. When Tai Ho joined the Toran Liberation Army, Yam Koo joined along with him.

During the war, Tai Ho met Kimberly, a stampmaker from Antei who came on to Tai Ho strongly. Yam Koo, knowing Tai Ho's weakness for women, tried to protect Tai Ho from Kimberly by staying with them.

Following the end of the Gate Rune War, Yam Koo lived near the shores of Lake Toran, where he continued to live a carefree life and enjoyed fishing.
