Yu-Gi-Oh! 5D's - Season 1 Episode 77

As Yusei and Akiza have a practice Turbo Duel, Leo ponders how he'd fare as a Turbo Duelist. Meanwhile, the Yliaster trio discuss their plans involving the Crimson Dragon, and another tablet crashes into the earth. Later at Duel Academy, a boy named Lester (one of the Yliaster emperors in disguise) enrolls into the school hoping to find out more about Luna, who soon falls in love with Lester. Leo gets annoyed with him asking her so many questions, so Lester uses an illusion to separate him from Luna, and takes her to his mansion. When Leo realizes he's been tricked, he sneaks into the mansion, where Lester shows off an Ener-D powered skateboard that can be used for Turbo Dueling, called a Duel Board, which he gives to Luna. Feeling jealous, Leo begs Yusei to build him his own Duel Board, and spends several days practicing. Luna later joins him in practicing, but they are attacked by another Duel Skater (who is really Lester back in his original dueling outfit) who traps her in a duel.
