Hold down & press up + HP,when the game start. You will have the highest chance of doing first attack. After doing that attack,grab your opponent with slamming power,go near + grab your opponent with slamming power,go near + grab your opponent with slamming power.....Lucky,you will get perfect. When you fight with El Fuerte,block.....When he land before you,you grab him with your slamming power,go near + grab him with your slamming power,go near + grab him with your slamming power....... Seth's matches-now it is not important,whether you do first attack or not. But,if you don't have any ultra or super to kill him during the 2nd match-Purposely lose to him.Because,you need to kill him with a super or ultra to unlock Oni.
