How do you get Blair in Yu-Gi-Oh gx duel academy?

Answer 1

After your encounterment with Bastion, (Required Level: 7)

You know you have triggered this event if Jaden wakes you up and

Banner has a meeting in the cafeteria. There, Blair mentions Zane,

getting Jaden interested, and Syrus mentions where he lives.

After that, you should proceed to the Blue male dorm. You and Jaden

will follow the mysterious red student inside as you all sneak into

Zane's room. The Red student makes a break for it upon being

discovered, so you and Jaden give chase. Zane and some Blue students

show up but let you go.

Chase the Red student to the north part of the island, look for a

random encounter. The hat comes off and it's a girl! You have to

face her deck. Win or lose, she tells you to keep her secret.

Unfortunately, Jaden shows up and she decides to leave the island

because her secret's out. You automatically head over to the harbor

to watch her go. Aww... that's sad.
