Duran is a mercenary swordsman from the Valsena, Kingdom of Green Fields (Forcena in the fan-translation) who proudly serves the wise King Richard. Duran's father Loki, a good friend of Richard's, was lost in a battle with the Dragon Emperor when Duran was still young. Soon afterwards, Duran's mother succumbed to an illness, leaving Duran and his little sister Wendy to be raised by their aunt Stella. One night, Duran is on guard duty at the castle of Valsena when the wizard Koren attacks the castle. Duran fights back, but is overwhelmed by Koren's magical abilities and is left for dead. After making his recovery, Duran vows to become the best swordsman in the world and to exact his revenge upon Koren. He then leaves for the Holy City Wendel to ask the Priest of Light about changing classes.
Duran shares many story elements with Angela, who comes from the Magic Kingdom of Altena which tries to invade Valsena. If either of them is chosen as the main protagonist in Trials of Mana, the main villain will be the Dragon Emperor and the final dungeon will be the Dragon Hole.
At first, Duran is a straightforward sword user with above-average Strength and Vitality stats. Upon changing classes, Duran can learn some magic to supplement his physical abilities. His Light classes learn primarily healing magic, whereas his Dark classes mainly focus on adding elemental attributes to weapons. Duran's Light classes have another benefit: they are the only classes capable of equipping shields, which greatly boost the wearer's Evasion stat.
Below is a list of Duran's classes. The first class change takes place at Level 18, while the second one takes place at Level 38, with the latter requiring specific items acquired from ??? Seeds.
Below is a list of skill attacks Duran learns across his different classes:
|L.1|| Cross Slash|
|L.18|| 3-Step Cut|
| Whirlwind Sword|
|L.38|| Flashing Sword|
| Magic Circle|
| Vacuum Sword|
| Eruption Sword|
Duran learns spells that can change the elemental properties of the characters' attacks, although his Light classes can also learn healing spells.
Below is a table of spells Duran learns across his different classes:
|L.18|| Healing Light|
| Stone Saber|
|L.38|| Holy Saber|
| Twinkle RainHeal Light++|
| Moon Saber|
| Dark Saber|
- Note: Duran gains the ability to multi-target with Heal Light when he changes class into a Liege. Likewise, his Saber spells will also gain the ability to multi-target when he changes class into a Edelfrei.
Seeking to find meaning in the fight, the Gladiator undertakes a journey of seeing struggle and competition underlying within all things in the everyday world. Even into honor and trust, the class ekes out the need to justify their efforts through coming out on top or with satisfying results brought about through proof through tests and testaments of action. To these ends, so has the Gladiator sought the powers of enchanting magic to bestow themselves with power of many varieties, and with a higher aptitude of strength than the Knight.
Long lived and weathered in a world of battle, the Edelfrei is a class of experience and wisdom through the heat and heart of the fight. Knowing the boundaries of life and death with familiarity, so does the Edelfrei precariously walk in and out of its realm frequently through their edification long done many times before, and does so without fear. Drawing upon lessons and teachings from these experiences, so has the Edelfrei tempered their body and mind to become a lone warrior with their own principles, and walks onwards to see the next day after the carnage of the day before. Rumors tell of warriors from a realm far from Fa'Diel saw their philosophies and virtuess passed into the world long ago, and those who had grown beyond their days as Gladiators saw their destiny encounter their ways into Edelfreis.
The meaning of the fight having eluded them long ago, the Duelist seeks but only one thing: Victory. For them, the fight is but a means to achieve that, and so the Duelist merely sees its occurrence as but a process and pastime of violent frequency to attain its graces. Easily lost in even the most savage instances of carnage and brutality, able to face the most harrowing of battles, and enter storm like tension without a wince, so have Duelists gained a reputation of being fighters of a dark strength derived from their world of deathly competition and merciless domination.
