Nervin, known as Blitz in the Japanese version and Yu-Gi-Oh! 5D's World Championship 2009: Stardust Accelerator and as Boyiston in Yu-Gi-Oh! 5D's Tag Force 4, is a character in Yu-Gi-Oh! 5D's, who is a resident of Satellite, and close friends with Yusei Fudo who is usually seen with Tank, Rally Dawson, and Blitz (who is known as Nerve in the Japanese version and Stardust Accelerator).
Nervin is a young man with dark blue dreads put in a ponytail, a green vest over a white dress shirt, cargo shorts, long socks, blue eyes and glasses.
Nervin along with Yusei Fudo, Jack Atlas, Rally Dawson, Tank, and Blitz lived together in Satellite. Jack left the group after having differing goals with Yusei. He would often help Yusei and the others when Yusei was building his first Duel Runner. He alongside the others, witnessed Yusei summoning "Stardust Dragon" for the first time with his completed Duel Runner.
Nervin, Nervin and Tank are first seen watching the Turbo Duel between Jack Atlas and Hunter Pace, before Yusei comes in to work on his Duel Runner. Shortly afterwards, when Rally Dawson comes to give Yusei a chip for his Duel Runner, he recognizes it as a new chip and asks Rally where he got it. Nervin, Tank and Nervin are later provoked into a fight by Lenny and his gang. Later Nervin, along with Rally, Tank and Blitz are captured by Iliaster and held captive to force Yusei to enter the Fortune Cup. After Yusei made it to the finals, Jack ordered that they be released, saying Yusei wasn't going to run away. Nervin and his friends are set free in a scrapyard with a monitor to watch the Fortune Cup final, and are surprised to see Yusei is dueling Jack and that Yusei defeated him.
After Yusei's Duel with Kalin Kessler, he and the others go and see Yusei to make sure he's alright, and find out by turning him over, that he sees a large metal shard impaled into his stomach. After their friend Crow Hogan takes Yusei away to get medical treatment, Nervin, Tank, Nervin, and Rally take Yusei's practically demolished Duel Runnner out of the B.A.D. area, but run into some trouble along the way. Luckily, Blister finds and saves them. They later go to where Yusei is being treated. When the black cloud that envelopes satellite comes he disappears. It is later found out from Rally that he was sacrificed to an "Earthbound Immortal". During Yusei and Roman's second Duel ends, he and all other people from Satellite sacrificed during the Summon of "Earthbound Immortal Uru" are revived.
Much later, he is seen cheering on Yusei in his duel with Z-one alongside Rally, Nervin, and Tank.  He is seen one last time with the rest of his friends in a truck driven by Tank, as Nervin is annoyed by the lane they were driving on the highway becomes prioritized by a duel. They are shocked to see it is Yusei and Jack dueling, as they pass.
