In the 45th episode of Yu-Gi-Oh Duel Monsters, titled Duel Monsters Quest 3: Master of Dragon Knight, we see the continuation of the Duel Monsters Quest arc. The previous episode ended with Yugi and his friends being transported to the world of Dungeons & Dragons, where they meet the Dungeon Master, a mysterious figure who tasks them with completing a quest. In this episode, Yugi and his friends are still in the world of Dungeons & Dragons and continue their quest to defeat the Three Swordsmen and acquire the final locator card.

As the group traverses through the perilous world, they come across the final Swordsman, who challenges them to a duel. However, this Swordsman is unlike any they have faced before. He summons a powerful dragon knight, which he fuses with to become the fearsome Master of Dragon Knight. Yugi realizes that he will need the full power of his deck if he is to stand any chance against this formidable opponent.

Yugi and the Master of Dragon Knight engage in an intense duel, with both sides unleashing powerful monsters and spells. The Master of Dragon Knight proves to be a formidable opponent, using his dragon knight to inflict massive damage to Yugi's life points. However, Yugi is able to turn the tide of the battle by summoning his signature card, the Dark Magician. The Dark Magician proves to be too much for the Master of Dragon Knight to handle, and Yugi emerges victorious.

After the duel, the Master of Dragon Knight reveals that he was actually a hologram created by the Dungeon Master as part of the group's quest. With the final locator card in their possession, Yugi and his friends are able to move on to the final stage of the tournament. But before they leave the world of Dungeons & Dragons, the Dungeon Master warns them of the challenges that await them and urges them to be cautious.

Overall, Duel Monsters Quest 3: Master of Dragon Knight is an action-packed episode that continues to ramp up the intensity of the Duel Monsters Quest arc. As always, the duels are the highlight of the episode, with the Master of Dragon Knight providing a unique and challenging opponent for Yugi to face. The episode also introduces us to the Dungeon Master, a mysterious figure who will undoubtedly play a bigger role in the season's remaining episodes.
