OVA
Description
Born in Pars era 293, Dariun was the nephew of the prominent military figure Vahriz. He distinguished himself early, becoming the youngest Marzbān commander during the Battle of Atropatene. Honorific titles like "Mardān fu Mardān" (Warrior among Warriors) and the Sindhuran-bestowed "Sher Senani" (Ferocious Tiger General) after combat against Bahadur attested to his widespread reputation for unparalleled combat prowess. His name, a variant of the Persian "Daryush," signifies "possessing goodness."

Initially serving King Andragoras III, Dariun faced disgrace for advocating a strategic retreat during Pars's second conflict with Lusitania. The king dismissed his counsel, but Pars's catastrophic defeat later validated his recommendation. Subsequently, Vahriz tasked him with protecting Prince Arslan. Dariun pledged absolute loyalty to the prince, symbolizing his oath with his sword, declaring: "The throne does not matter. It is for the sake of this man himself that I will continue to wield my sword." His commitment centered on safeguarding Arslan personally.

Physically, Dariun possessed a darker complexion relative to other Parsians. Adaptations depict him with either short hair or a long ponytail. He wore iconic black-and-red armor, occasionally accented with metallic elements, drawing inspiration from Stendhal's *The Red and the Black*. A master of spear, long sword, and bow, he fought with disciplined ferocity, often mounted on his warhorse Shabrang. His tactical acumen and fearsome presence frequently demoralized opponents, sometimes prompting desertion.

His relationships included a longstanding friendship with the strategist Narsus, marked by sarcastic banter, and professional camaraderie with fellow generals Kubard and Kharlan, the latter ultimately betraying Pars. Historical accounts note an unresolved incident involving rejection by a Serican princess, though romantic subplots remain undeveloped.

Throughout Arslan's campaign to reclaim Pars, Dariun evolved from a disgraced knight to a cornerstone of the prince's inner circle. His role expanded beyond bodyguard to trusted advisor, culminating in his appointment as Erān of Pars—overseeing the kingdom's military—after Kishward's retirement, reflecting his growing political and strategic responsibilities.

Adaptations consistently portray his core traits: stoicism, martial excellence, and unwavering loyalty. Design elements vary; older OVAs feature short hair and simpler attire, while newer iterations emphasize detailed armor and a ponytail. Hiromu Arakawa's manga adaptation specifically reinforced his darker skin tone. Spin-offs like the video game *Arslan: The Warriors of Legend* highlight his combat mechanics through polearm and cavalry movesets.
