He's the second bachelor to have a monster form, which you must defeat in order to date him and to continue on with the game's plot. He is light-hearted and prone to making fun of serious people, but in actuality cares deeply about others. Leon's monster form originally hailed from the tower-like temple dungeon known as Leon Karnak, which is situated far West from where Selphia is.
Before becoming a guardian, Leon was a dragon priest to Ventuswill. When traversing the Forest of Beginnings at Leon Karnak, it is revealed that Leon chose to sacrifice himself both for his duties and to save Ventuswill as a friend.
After being brought to town, Leon moves in with Xiao Pai and Lin Fa. Although Leon finds the antics of both the mother and the daughter amusing and quickly takes to teasing them, he becomes fairly close to them. However, he sees them more as friends than as family members. Leon can also be seen fishing during most mornings near the pond in Selphia's residential area.
Leon possesses traits of his monster form compared to any other guardians. He has fox ears, a fox tail, and runic patterns etching his face.
Leon was born hundreds of years before the main plot into an unnamed family. He was childhood friends with a girl named Maria, and even agreed to marry her eventually. At some point, he became a dragon priest and would often listen to people's problems.
He decided to become a Guardian and was sent off by his friends and family. His body was fused with the earth's runes to keep sending power to Ventuswill. He slept for hundreds of years until being awoken by either Lest or Frey.
