Yu-Gi-Oh! GX - Episode 042

Duel Monsters Spirit Day, known as '''School Festival Duel! Blamagigirl's Intrusion''' in the Japanese version, is the forty-second episode of the Yu-Gi-Oh! GX anime. The annual school festival has arrived, and each dorm puts on a celebration. A girl resembling "Dark Magician Girl" appears, and ends up dueling Jaden Yuki.

Summary
A strange, yellow ball of light was floating around Duel Academy. Apparently, it was Duel Monster Spirit Day, the day where students appreciate the Duel Spirits and dress up as their favorite monster. The yellow light was the spirit of the "Dark Magician Girl". She wanted to stop by the Academy and make Spirit Day a day they students will never forget.

Meanwhile, all around the school, students were celebrating spirit day. Chumley Huffington and Syrus Truesdale worked together to create a duel arena outside of the Slifer Red dorm, for Syrus’ costume duel. The remaining holders of the Spirit Keys meet outside the dorm to discuss what Atticus Rhodes had said in regards to Professor Banner - he had been the one to instruct the students to go to the Abandoned Dorm. Banner had since disappeared, so they believe he is working for the Shadow Riders. Chazz comes up with the idea of using Banner's cat Pharaoh to find Banner, but is unable to locate him either. Having no other options, they agree to just attempt to enjoy Duel Monsters Spirit Day. Syrus attempts to find someone to dress up as "Dark Magician Girl" for the costume duel. Jaden Yuki is unable to decide on a costume, and instead combines pieces of several. He ultimately ends up a combination of Saggi the Dark Clown", "Breaker the Magical Warrior", "Obnoxious Celtic Guard" and "Gearfried the Iron Knight" costumes. Chazz dresses as "XYZ-Dragon Cannon", Alexis Rhodes, Mindy and Jasmine go as "Harpie Lady Sisters" and Bastion Misawa dresses as "Amazoness Tiger". Ms. Dorothy dresses as "Dark Magician Girl", much to everyone's horror.

They are approached by someone who appears to have a perfect "Dark Magician Girl" costume, and she agrees to duel Jaden. After the duel, everyone was curious as to who exactly was the Dark Magician Girl. Syrus figured it out that she was the spirit of Dark Magician Girl and hoped to see her again someday. That night, her spirit returned and gave Syrus a kiss before departing.
