hidden characters
I finished the game with Jaden, Syrus, Chazz, Tinia(shadow raider) and Jewels(an Obelisk blue girl) and I unlocked Emperor.Umiuma, Mokuma and Senjome.
You will find Senjome at the obelisk blue boys dorm and he will ask you to go with him for a tag duel against Emperor.Umiuma and Mokuma. When you win, you will gain Senjome's trust and will be able to duel with him to finish the game.
Hope this helps!
