UPDATE: Bloody Palace beaten, S ranked.
So I'll start off by saying DrPirate is by far the most accomplished person on my friend's list.
I've currently beaten Devil Hunter and Son of Sparda, doing Dante Must Die right now. I have no D's, very few C's, many A's and some S's, and a few B's.
Highest I've gotten to in Bloody Palace is 36 (mind you I've only played it twice).
I've cleared every secret mission (they were surprisingly not too hard, considering most of them had some kind of exploit to make them incredibly easy (PANDORA, *cough*)), and my DT gauge is maxed. I have well over 100,000 proud souls and probably closing in on 1,000,000 red orbs. For Nero, I need to buy all the Table Hoppers, for Dante, I need to buy both Level 3 charge shots (his charge shots aren't that useful) and that move where he throws Rebellion into the enemy (had it once, never used it). Everything else has been maxed.
I'll also share one of my favourite strategies:
My preferred Blitz killing strategy (Nero): I guarantee two things: You will get to SSS if done right, and you shouldn't get hurt either. Charge shot level 3 and hit him. Do this once or twice more, while evading him, until his lightning shield is gone. Activate DT (hopefully your gauge is full or near full) and buster him, while bustering immediately spam your gun button to drill him with Yamato shards WHILE performing the buster attack. Wait for him to land properly and repeat this yamato-buster TWICE more. Then, he'll start to redden. Charge shot level 3 really quickly and pop it into him. Back away, and watch him explode and your style points should blitzkrieg to SSS.
