Lock - S3.E23

Kai meets with Takuto and tells him about the incident with Naoki. Takuto explains that it is the work of Reverse, a phenomenon created by the evil Void in its quest to envelop everything in darkness. He further elucidates that those who are Reversed will lose their souls and become engulfed with Void's energy if they lose to a Reversed fighter. It is then revealed that Takuto has been Reversed and is now an agent for Void. The two engage in a cardfight, and Kai is surprised to see Takuto's deck representing Link Joker, a never-before-seen clan that acts as the harbinger of Void. As the fight progresses, Kai is shocked by the terrifying Lock effect of Link Joker; his units are sealed away from being used until the end of his turn.
