Osk is a merchant of the Baharuth Empire and promoter of the Martial Lord of the Grand Arena.

The fourth season of Overlord.
 
E-Rantel, the capital city of the newly established Sorcerer Kingdom, suffers from a dire shortage of goods. Once a prosperous city known for its trade, it now faces a crisis due to its caution—or even fear—of its king, Ainz Ooal Gown. To make amends, Ainz sends Albedo to the city as a diplomatic envoy.
 
Meanwhile, the cardinals of the Slane Theocracy discuss how to retaliate against Ainz after his attack crippled the Re-Estize Kingdom's army, plotting for the Baharuth Empire to take over the Sorcerer Kingdom. However, when Emperor Jircniv Rune Farlord El Nix arranges a meeting with the Theocracy's messengers at a colosseum, he is confronted by none other than Ainz himself.
 
With their secret gathering now out in the open, the emperor and his guests learn that Ainz has challenged the Warrior King, the empire's greatest fighter, to a duel. With Ainz's motivations beyond his comprehension, Jircniv can do nothing but watch as humanity's future changes before his very eyes.

Benoît Allemane is a French actor who specialized in dubbing. He is known for being the French voice of Morgan Freeman. 

After his graduation from the *École Nationale de Théâtre de Strasbourg*, he moved to Paris where he performed various plays and came into contact with voice acting. He did not feel very comfortable doing this so he gave up to focus on others aspects of his profession. 

Around 10 years later he gave dubbing another try after gaining experience from doing post-synchronization for the local television and never stopped since.
