Yam Koo
“ Here we go again with Big Brother's madness. ”

Yam Koo is a fisherman and the sworn brother of Tai Ho. The two met during a gambling brawl and have been friends ever since[1]. 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"[2].

Yam Koo was swept away in one of Tai Ho's whims when Tai Ho and Yam Koo escorted McDohl to Toran Castle. When Tai Ho joined the Toran Liberation Army, Yam Koo joined along with him.

During the war, Tai Ho met Kimberly Yam Koo, knowing Tai Ho's weakness for women, tried to protect Tai Ho from Kimberly[3].

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[4] and enjoyed fishing[5].

Yam Koo followed Tai Ho to the City-State of Jowston, helping Tai Ho escape his now-wife Kimberly. Tai Ho and Yam Koo met the hero in Coronet Town and helped transport his party to Kuskus Town.

Later, Tai Ho agreed to join the New State Army, and Yam Koo agreed to go along, with some reluctance[6]. At the New State Army Headquarters, Yam Koo showed a passion for fishing, even encouraging the hero to get into the sport[7].

Following the war, Yam Koo returned to the Toran Republic, where he enjoyed a life of fishing in Lake Toran[8].
