Liukan (リュウカン, Ryuukan) is a supporting character in Suikoden who makes a cameo in Suikoden II. He is considered to be the finest physician in all of the Toran Republic.
Please take care. Even I, Liukan, cannot raise the dead.
Liukan is a famous doctor purported to be so old that even he himself does not know his age. It was said that any ailment could be cured if you took the medicine he prescribed and he was known as the "holy doctor" due to his prowess.
However, despairing that he could not treat the turbulence in people's hearts and minds, he could not fight his own pessimism that led to him abandoning civilization and secluding himself in his hermitage deep in the mountains, despairing about the troubled times he lived in.
In particular, he was able to neutralize the effects of Milich's poison fog and would later work to cure the dragons when they fell into a deep sleep. He would also fight in battle, using the walking stick that he normally used for balance to strike his foes. At Toran Castle, he spent his time with Fukien, the two sharing their insights and lamenting the loss of life caused by war.
Following the war, he opened up a clinic where he worked to save many lives. Although once more treating patients, Liukan still lived an isolated life, rarely venturing down from the mountains.
Liukan is sometimes referred to as the "Holy Doctor."
Liukan's weapon upgrades as Stick, Oak Stick, and Ebony Stick. Both of these types of wood have medicinal uses - Oak bark has been used by herbalists for years as an astringent, and the leaves and other parts of the trees of the ebony family were traditionally used to treat intestinal parasites, wounds, dysentery, and fever.
