- "The main character of the story who is a blood descendant of the Belmont clan, renowned for being the fiercest of vampire hunters. The Belmont clan's magical power is partly derived from blood ties to the Fernandez family.
Having abilities considered prodigious even among his family members, he inherited the whip passed down from his forefathers at the young age of sixteen and has inherited the title of Vampire Killer."
- —Castlevania: Harmony of Dissonance booklet description.
Juste is considered powerful even amongst his family for his superb magical talent derived from the Belnades family. He is able to best his friend, Maxim Kischine for control of the Vampire Killer. Although Juste and Maxim only ever met once during their competition to see who would be the next weilder of the whip they felt a connection. This was probably because Intuitively they both knew their destinies were intwined. After being beaten rather badly by Juste in the competition, Maxim then goes on a training expedition to better himself. He returns two year later, wounded and amnesiac and claims that his and Juste's mutual friend, Lydie Erlanger, was kidnapped and taken to Castlevania. Juste arrives with wounded Maxim but goes alone when Maxim needs to stop and recover. Chased inside by a giant undead knight, Juste has no other choice but to find Lydie with only his trustworthy Vampire Killer whip and a bracelet that both he and Maxim share.
After journeying through Dracula's castle, Juste learns what truly happened during Maxim's training expedition. Maxim had been collecting Dracula's body parts in the hopes of resurrecting the Dark Lord and defeating him, much like how Simon defeated Dracula. However, this plan backfired, and Maxim ended up getting possessed by the dark power of Dracula's remains. Because of this Maxim ended up developing a second personality - a dark Maxim, through which Dracula's will spoke, and Juste would meet in the Sky Walkway. This evil side of Maxim was the one who kidnapped Lydie and left Maxim with his amnesia so he could lead Juste to the castle. Another result of this divide was that the castle has been split as well: there were two castles, or rather two sides of the same castle, connected by portals. They were named Castle A and Castle B, each representing one side of Maxim's mind, as the castle's creator.
The player's actions and whether or not Juste was wearing both Maxim's and his own bracelets affected Maxim's fate, giving the player access to multiple endings.
- Juste means Righteous in French.
- Richter Belmont is believed to be the son or grandson of Juste. Juste's fight takes place in 1748 at the age of 16 while Richter is 19 in 1792. This means, if still alive, Juste would be 62 when Rondo of Blood takes place and 43 when Richter was born.
- Since Dracula Wraith was not real Dracula, Juste has not fought with Dracula.
