Information about Fraud, Treachery and P-3 may be incorrect, if provided, as they have not yet been released. There will also be no mention of P-P, P-S, or act 4 and further, since these are all speculations made by the community and are either not confirmed by Hakita to happen, or confirmed by Hakita not to happen.

P-ranks are earned when the 3 style categories(time, kills, style) have reached S rank when you beat the level. P-ranks also require you to never restart during the run, so checkpoints are useless during these runs.

P-ranks are required to enter P-1, P-2, and P-3. For P-1, you need to p-rank all levels in the prelude and act 1. For P-2, you need to p-rank all levels in act 2 and beat P-1. And for P-3, I believe you will need to p-rank all levels in act 3 and beat P-2.

Un-equip all but 1 or 2 weapons. This is because if you only have one weapon, your fresh-o-meter(That's what I'm calling it) will never drop below fresh(1.50x). If you have 2, it won't drop below used(1.00x). Once you equip 4 weapons, your fresh-o-meter can reach dull(0.00x), making your weapons give no style.

Arms do not count toward the weapon count and give style independently of the fresh-o-meter, meaning you can use the feedbacker, and therefore, parry. This is one of the best ways to earn style, as you can parry almost anything in the game, hell energy, dropkicks, V2's bullets, even whatever the hell the shotgun fires!

If you don't wanna uneqiup your weapons, then just... don't. I'm not saying you have to, but you guys treat it like I am. This has led to the conclusion that:

You guys are stupid.

If you're using revolvers/shotguns, set last used weapon to the same key as primary fire, and remember, tap it, don't hold it. This makes it so that the revolver and shotgun fire faster if you time it right, and makes it so that almost every shot you hit gives the +QUICKDRAW style bonus, which gives 90 style points(if fresh-o-meter is on fresh), almost as much as +PARRY, which gives 100 style points.

Sadly, you can no longer set primary fire and last used weapon to the same key. So, you'll have to press them both individually instead of being able to press just one button.

If this is too fast for you, or you can't hit any shots, I recommend using auto aim, or enemy silhouettes/outlines. If you don't want to, then don't, I'm not stopping anyone.

Have fun! If this isn't fun for you, then don't try it. Besides, if it's not fun, why bother?
...well, I mean, you could brag about it. So there's a reason to use this method, to brag and make yourself at least seem like the better of your friends at the game.
