Yu-Gi-Oh! 5D's - Season 1 Episode 86 Duelist for Hire

Yusei arrives in a desert town called Crash Town, after receiving a letter from a woman named Barbara that Kalin was in trouble. She explains that in this town, there are battles at sunset between the Malcolm family and the Radley group. Yusei is surprised to find Kalin siding with Radley's group, and notices a change in his personality. Kalin uses his Handless Combo and quickly defeats Malcolm's challenger, who is taken away to become a slave in the mountains. Yusei tries to reach Kalin, but he doesn't answer him. Barbara tells Yusei the only way to save him is to beat him in a duel to separate him from the Radley family. Yusei decides to join up with the Malcolm family, earning his place by defeating three of Malcolm's men in one turn, with his Nitro Warrior.
