So I gave CS Score Attack mode a shot for the first time today... Got to Hakumen with Jin and then gave up in disgust because he was raping me so outrageously I didn't feel like I stood a chance of winning in a million years.
I then looked around online for tips on beating Score Attack and found Beginner Mode Tager mentioned, so I gave that a go. Once I got the hang of the BM controls, he felt hilariously broken and I found myself raping everyone including Hakumen... but then there was Hazama, who was an utter bitch even as Broken Mode Tager, and so I gave up on that too in the end (though I could probably have beaten him if I'd carried on long enough...)
But yeah, I figure if I can't even handle Score Attack Hazama with Broken Mode Tager, my chances of ever unlocking anyone else's Unlimited forms are approximately minus zero. I'll probably cave in and buy the DLC unlock at some point, much though the thought pains me ~_~
...On the bright side, I did at least manage to beat Arcade Mode with Rachel without switching the difficulty down to Normal. =D (Still on single-round mode, but hey, I'm proud of my small victory.)
