The Ghost of Tsushima story is centered around Jin Sakai's fight against the Mongols on Tsushima. Jin is faced with a formidable enemy that challenges the traditional samurai way of life. As the Mongols overrun the island, Jin has to make difficult choices. He starts to use guerrilla - like tactics that are not in line with the strict samurai code he was brought up with. His journey is one of self - discovery and adaptation. He also has to deal with the moral implications of his new methods of fighting. For example, some of his actions might be seen as dishonorable by the traditional samurai standards, but he does it for the greater good of saving his island and its people.
