The first game does this better in my opinion, since you can't just mindlessly spam the same attack because there will be a combo score reduction.
SSS Rank No DMG is the equivalent to Pure Platinum medals/trophies, that you can get by taking no DMG and having a high combo score as well as beating 'missions' fast. There is not really a hardcore mode and there isn't one in DMC either (apart from Hell and Hell). It also feels like I'm playing Bayonetta herself when I'm being flashy, since Bayonetta, the character, is stylish and values appearance and looks. Launching angels with a wicked weave, following up with ABK and then continung to launch them up even further and do all kinds of crazy stuff just feels incredibly satisfying. Mostly because it's fun to have some variety in your combos and make it as flashy as possible.
