Ike begins his journey as a member of a band of mercenaries led by his father, Greil.
But when the group is drawn into a war between the kingdoms of Daein and Crimea, Greil tragically loses his life, and the young Ike must shoulder his father's burdens. As the new leader of the company, Ike strikes a bargain to protect Elincia, the princess of Crimea, from Daein troops. He supports her through the war and, wielding a sword of great personal significance that was once brandished by an ancient hero, he ultimately defeats the Mad King Ashnard and brings Daein's war of aggression to an end. As he continues to train and hone his skills, he becomes known as a man who can be relied upon to rescue any friend from trouble, no matter how dire—and goes on to play a key role in a conflict that will determine the fate of the entire continent.
