Yu-Gi-Oh! 5D's

Realizing Luna and Leo are in trouble, Yusei, Jack, Crow, and Akiza head off to find them. Luna summons out Ancient Fairy Dragon, but it is soon absorbed by Machine Emperor Skiel Infinity. As Yusei and company can only watch, Leo recognizes his opponent as Lester, but Lester states the recognition of his identity has already come to late for them to do anything about it. Luna soon takes some damage in order to protect Leo from Skiel's attacks. Leo summons out Power Tool Dragon, and using traps and monster effects, manages to retrieve Ancient Fairy Dragon. Lester upgrades Skiel and defeats Leo, knocking him off the bridge, but the Crimson Dragon appears and saves him. Luna's counterattack fails, but her Duel Monster spirits prevent her from being hurt, after she loses. When the group try to investigate Lester, they find his mansion gone, and that no one at Duel Academy remembers him. Spurred on by this attack, Yusei becomes determined to learn the Accel Synchro.
