One day, during dinner, Professor Banner announced that a new student was joining Slifer Red, Blair. Blair was a transfer student who passed all of his entrance exams with high scores, so he would only be in the dorm for a short time. He was only in the dorm because of the rules. The following day, Chancellor Sheppard announced that the upcoming duel between their school and their rival, North Academy. A student will be chosen from both schools to represent them and duel to see who is the best. Jaden wanted to get in on that and Blair seemed to be acting strange when looking at Zane.
Afterwards, Jaden, Syrus and Chumley were walking outside when Jaden saw Blair sneaking around the Obelisk dorm. Jaden secretly followed him and watched as Blair climbed up a tree to a balcony that was Zane's room. Blair went into Zane's desk drawer, took out his deck and started to fondle them gingerly. Jaden found it to be weird and when Blair saw him, he ran. Jaden tried to grab him but only pulled off his hat and revealed that Blair was actually a girl. She ran off and Jaden was caught by Zane and his friends. They accused him of trying to steal the deck, but Zane let him go. That night, he told about the incident to Alexis at the lighthouse. Zane apparently, found Blair's brooch and figured out her secret. Meanwhile, Syrus and Chumley noticed that Jaden wasn't in the room. He was outside at the beach with Blair and talking about how he know's her secret. Jaden didn't want to know why she was at the academy and disguised herself because he figured a duel would be the the only way to find out. Syrus and Chumley watched the event from the cliff above.
Blair: summoned Maiden in Love (400), who's special ability stops her from being destroyed in battle
Jaden: summoned Avian (1000) and attacked Maiden, which activated her other ability. When she's attacked, the attacking monster is given a maiden counter.
Blair (3400 LP): attacked Avian with Maiden, which failed. When a monster with a maiden counter is attacked by Maiden, that monster becomes Blair's. Now she controls Avian and used him to attack Jaden directly and ended her turn with one face down card.
Jaden (3000 LP): summoned Sparkman (1600) and attacked Avian, but Blair used her trap card, Defense Maiden. Her Maiden took the attack and gave Sparkman a maiden counter.
Blair (2800 LP): played the magic card, Happy Marriage, which gave Maiden 1000 attack points. She attacked Sparkman and put him under her control. Blair used both Sparkman and Avian to attack Jaden directly.
Jaden (400 LP): summoned Burstsinatrix (1200). Since Burstsinatrix was not attacking, she was not affected by Maiden's abilities. Jaden played the magic card, Burst Return, which returns all monsters but Burstsinatrix back to his hand. He then used Polymerization to fuse Avian and Burstsinatrix to summon Flame Wingman (2100). Wingman attacked Maiden and destroyed her, winning Jaden the duel.
Afterwards, Zane confronted Blair and revealed that Blair had a crush on him, but she shouldn't try to pursue him because she was too young. The next morning, the school had Blair take off on the next boat off the island. She started to build a crush on Jaden and promised to write to him everyday.
