Denis (デニス, Denis, Russian: Денис) is an old friend of Simon Brezhnev and the owner of Russia Sushi. He works inside Russia Sushi as the chef while Simon usually waits on customers.



Denis is a large white man usually seen working behind the counter as a chef in Russia Sushi. As such, he is always seen wearing the Russia Sushi uniform.


As a result of his past in the Soviet Union, Denis, like Simon, is a pacifist and tries to stop conflicts before they start. He appears wise and well-connected, as he is able to offer sound advice and has the contact information of Izaya and Haruya Shiki. Unlike Simon, Denis speaks fluent Japanese, but he speaks up less than his partner.

Although Denis' strength is unknown, he is shown to have significant skill with knives, skills acquired both in battle and as a sushi chef.


Not much is known about Denis' past other than he and Simon were former special ops soldiers for the Soviet Union. Under Drakon, they trained his daughter Vorona in combat and weapons. Growing weary of a life of fighting, along with the collapse of the Soviet Union, he and Simon immigrated to Japan and opened a restaurant and have remained there for several years.
