Acceleration

Wanting to understand what Turbo Duelists feel, Akiza decides to apply for a Turbo Duel License. Despite initially making lots of mistakes, her determination, along with Yusei's tutelage, allows her to pass the initial exams. Yusei also takes her rollerskating to help her learn how to ride backwards. Yusei then builds her a proper Duel Runner, with the help of Jack and Crow. To obtain her license, she has to beat Trudge in a qualification duel, though she initially has trouble getting to grip with Speed Spells, and her Black Rose Dragon gets beaten. However, she manages to turn it around and summon her Splendid Rose. Some guys, who were furious about losing to Akiza in the initial exams, activate a trap to trip Akiza up. However, using the skills Yusei taught her, she evades the trap and defeats Trudge. With her license earned, Yusei welcomes Akiza to the world of Turbo Dueling. Meanwhile Jack beats up the guys that activated the trap and calls Akiza his friend.
