Hint: Fight Kazuya using both the same costumes:
Unlock Kazuya and his purple outfit. Choose anyone except Kazuya. Win both rounds with person who you are playing. Next, lose both rounds of the next fight. Choose Kazuya with the purple costume. Defeat all the characters and get to Kazuya. You will see that Kazuya is wearing the same costume as yours. The reason why you have to start with someone and lose is because originally Kazuya is one of the bosses. If you start with Kazuya, Heihachi will take Kazuya's place.
