A free spirit who hates the strict rules of the household where he was constantly told what to do and not do, Jesse's father was a high-ranking Zofian nobleman, and he was in fact friends with Clive and other nobles around his age. There were high expectations for him due to his skill with the sword, but trouble arose with the birth of his younger half-brother, as Jesse himself was born to a low-ranking concubine rather than a proper wife. Most of their vassals hoped Jesse would succeed his father, but Jesse decided instead to abandon his family name and run away for the sake of his sickly brother's future.

At some point in time, Jesse encountered Silque being kidnapped by bandits. Realizing her plight, he rescued her and then accompanied her during her travels for a distance, parting at Zofia Harbour. Later on, Jesse attempted to save Est from Grieth, but was captured and imprisoned at the Desert Stronghold. When Celica's party frees him he then joins their team.

After the war, Jesse made his own nation in Grieth's land, joined by Saber and Kamui. He became known as the "Desert Mercenary King".
