The Last Duel! Team Satisfaction is the fifty forth episode of Yu-Gi-Oh! 5D's.
The last stretch of Yusei and Kiryu's duel has begun. As in their previous match, Kiryu uses his handless combo and Infernity monsters to attack. On the other hand, Yusei duels Kiryu, his determination to save him fueling his resolve. If the unfortunate event that befell Team Satisfaction was the root of the two's fight, Yusei believes that he can surely save Kiryu in this duel.
