Right, I think I completed Red Steel but it only says 77%. Is it because I didnt do all the training or did I mess up the end?

You know when you beat Tokai and he says he can save that other guy. Well I couldnt stop him passing and he killed Tokai. And then the credits came up... Is that the end or is there another ending? Do I have to start the game all over again?

PS. Mint game, really enjoyed it! Was thinking about selling it after I completed it but I think Id play it again!!!
