"Sinister Secrets, Part 2" is the one-hundred and ninety-seventh episode of the Yu-Gi-Oh! anime. It first aired in Japan on March 24, 2004 and in the United States on October 8, 2005.
The Duel between Yami Yugi and Leon von Schroeder continues. Leon activates "Golden Castle of Stromberg", which unbeknownst to him was reprogrammed by his brother Zigfried with a virus that infects Kaiba's computer databases. In order to save Kaiba's company, Yami must find a way to destroy the seemingly indestructible card and win the Duel.
Leon manages to gain the upper-hand in the Duel and explains that he found consolation in fairy tales when no-one would mind him, and was fascinated by them. He wrote a letter to Pegasus and asked him to produce "Fairy-tale-themed" cards. Yami Yugi makes a comeback by using "Mirror Force", but Leon quickly Special Summons two of the destroyed monsters. Rebecca remarks that Leon's strategy is strong, and that she is unable to see any flaws on it. Yami Yugi then uses a combo to quickly Summon "Dark Magician Girl", which is one of Leon's favorite monsters.
Leon draws and activates the Field Spell Card given to him by Ziegfried, "Golden Castle of Stromberg". When he does, his Duel Disk frizzles, which catches the attention of Seto Kaiba, Professor Hawkins and Solomon Moto. Solomon and the Professor admit knowing about the card, but weren't expecting it to show up in such a place. Duke has a hunch, which is confirmed: "Golden Castle of Stromberg" was a single-print rare card made by Pegasus for test purposes and prestige only. It was the reward in a tournament (named "Fall Cup Duel Project" in the Japanese version) several years ago, and was never meant to be released or played in tournaments. Seto notes that with the influences of the Schroeder family, getting it must've been easy. Mokuba adds that, since the card holds such a status, the "Solid Vision System" should have never accepted it. However, he realizes something, which Seto confirms: the Duel Computer's Limiter has been tampered with so that it's recognized as a legal card. Kaiba demands to know if that was Zigfried's true goal, which Zigfried responds to by shrugging. Zigfried smugly thinks to himself that Kaiba can't escape his trap.
After finding out his card is illegal, Leon looks unsure. Zigfried tries to assure him by claiming that, since the card is on the field, it's now legal and winning is what matters for their family. Yami Yugi accuses Zigfried of staining both the Duel and the "souls of us Duelists", saying he doesn't have the qualification to be a Duelist. Zigfried disregards the accusation, seeing Duel Monsters as being a mere game. Yami Yugi claims that he's stained the sanctity of the entire tournament: the Duelists who took part in this tournament and everyone who came to cheer, the fans of Duels scattered around the world and the heart of Leon, who was fighting for his sake. Zigfried sees it as "playing the hero" and tells Yami Yugi that he's "not mature enough".
Leon tells Zigfried that it'd seem he doesn't believe in him after all, and that's why he's doing this. Leon refuses to play foul, so he activates "Mystical Space Typhoon" to destroy it. However, since "Golden Castle of Stromberg" cannot be destroyed by Spell and Trap Cards, it fails. Solomon and the Professor catch on: the card's text data has been rewritten. Suddenly, a nearby TV screen frizzles. Zigfried asks Kaiba to remove the limiter if he thinks it really bothers him so much, as the card itself is a switch. Upon its activation, a virus program is engaged.
Kaiba orders from the anti-virus program to be engaged, but Zigfried deems it to be too late: all programs will be erased at a great speed, and all of the Duel monsters data will be gone. Leon, taken aback, tries to surrender the Duel, but Zigfried claims that it won't halt the virus. There's only one way to stop it: destroy the Golden Castle! Yami Yugi encourages Leon to keep on, and he promises to find a way to destroy it. He rallies for him to show Zigfried "the glory of Duelists" and claims that they'll get rid of this infamous trap.
