I've included details about each fight/Verse in the description, please read for more details:
Really brutal chapter to Pure Platinum. There's multiple difficult fights where it's hard to avoid eating a hit, and then there's several fights with demanding combo requirements. And it's lengthy; a screwup at any point means redoing it from scratch. I had at least fifteen restarts on this chapter in trying to Pure Plat it here.
I also wanted to show out all the things you can examine here in case anyone's missed them which meant re-examining them all on each attempt. Oof.
Verse 1: Simple. Two doggos with lots of space to blast 'em.
Verse 2: Don't accidentally hit one of the flaming Ardors. Kilgore as usual is ideal for keeping them at bay, as is Tetsuzanko to knock them away with the punch Weave.
Verse 3: Not too bad, don't get stepped on by the Braves, and don't drop your combo.
Verse 4: Gracious and Glorious + area with a high ceiling + Durga Lightning on the feet + Eternal Testimony = feather spam for the win. I use the Braves' axe to recover magic for the next Verse.
Verse 5: Nightmarishly hard to get the Platinum Combo without using either Gaze of Despair or Bracelet of Time. Even without dropping my combo I had multiple restarts here. Possibly the Verse with the strictest combo requirements in the entire game...
Verse 6: Using gaze on the Enchants gives you a big combo, which gives you leeway as to how you kill the Gracious and Glorious. There's no option to feather spam them here; the ceiling's far too low. Shotguns are good for stunlocking them but risk getting you a mere Gold for combo as I discovered from several attempts where I had to restart the chapter. ;w;
Verse 7: Grab an angel weapon here. It's super useful for the Justice fight in Verse 10.
Verse 8: You gotta be fast and efficient. Dropping your combo while you're trying to dodge shots will screw you over, too. I'm not using autofire here and just mashing the Shoot and Punch buttons as fast as I can.
How do you dodge his giant laser beam attack? Are you supposed to interrupt it with damage? I can never dodge it, and I always have to use Pulley's Butterfly or get lucky with Bat Within. :'(
Verse 9: Easy. It's a fight with no gimmicks other than the flaming Ardor siege I deal with via dodge offsetting to fire off rockets. You seem to have plenty of time and a generous leeway for score to get Pure Platinum. The hardest part is remembering to backtrack and do the Alfheim!
Verse 10: I use Bracelet of Time and the angel weapon from Verse 7 to burst down Justice. If you forgot the weapon, you can also stunlock Justice by using charged feather rings in his face pretty effectively, the tentacles have a hard time hitting up close. If you land on this head with a charged feather ring it instakills his last phase.
Verse 11: Another very strict Joy fight like Verse 5. I use Gaze of Despair to build magic and ensure my combo's a Platinum. It got a little out of hand with respawns, so I busted out Shuraba slashes to finish them off just to make sure it was a Platinum time.
Verse 12: Kill one Joy, then use Gravity Reset to help fly to the next two platforms quickly. I thought I botched this attempt when the Joy got knocked off the ledge, but fortunately it still was enough combo to Pure Platinum. ^w^;
Verse 13: Same as the last Golem, just with a couple new attacks. The centipede attack's the most dangerous. I screwed up and combo drop here but it still somehow manages to reach Platinum combo. Phew.
Verse 14: PKP charges with Kilgore to fire rockets into Prudence's stinky face seemed to work well. Visibility sucks so it helps to learn to dodge based on the audio cues.

This Bayonetta playthrough features the secret character "Little King Zero", who is unlockable by clearing the bonus chapter "Lost Chapter: Angel Slayer". Little King Zero is the hardest character in the game to get Pure Platinums due to his innately equipped Infernal Communicator interfering with the use of both Pulley's Butterfly and Sergey's Lover. His minor advantage of very slightly faster running speed and slightly improved magic gain per hit (mostly noticeable when using Scarborough Fair, Handguns, or Bazillions) do not make up for these disadvantages.
This playthrough gets a Pure Platinum (no damage taken in combat, Platinum rank time and combo on every fight) on each chapter while showcasing all the cutscenes as Little King Zero, without ever resorting to the checkpoint restart exploit. Most playthroughs on KZfaq resort to this exploit, where you can immediately pause the game, select Quit to Title Screen, and then Continue to restart any fight where you get hit, or if you're worried your combo score or time are too low to get Platinum. It's easy to spot the jump cuts in Pure Platinum runs where players resort to this exploit before difficult fights.
