Breakdown of extra lives in extra stages:
EoSD: 2, midboss and right before boss
PCB: 5, midboss, boss after first spell and 3 for point items (200, 500, 800)
IN: 4, midboss, right before boss and 2 for point items (200, 666)
PoFV: potentially infinite, every 5,000,000 points
MoF: 3, midboss and 2 for score (30 million and 100 million)
SA: 3 (or 4, but then you don't need it) off life pieces (4 is if you don't die to Sanae or Koishi until Subterranean Rose)
UFO: 2-4 (midboss, boss, 0-2 off of UFOs)
GFW: depends on how much you freeze, but a ton.
TD: 2-3 (depends on trance placements-but 2 is a freebie)
On Kanako, I bomb almost everythign she has in actual runs, but in stage practice I reliably get her 1st spell, 2nd nonspell, 2nd spell, 3rd nonspell and 4th nonspell. Her 1st nonspell, 4th spell and 5th spells are autobombs. 3rd spells is bomb if I feel trapped. She's not the easiest to avoid, but to survive, she is very easy to survive against aside from VoWG, which gets hard to dodge halfway through.
For Kaguya, I figured out a tactic for her opener to make it easier, but her first spell is autobomb or death. beyond that, I bomb if I feel i need to-said 1 death lunatic Kaguya had no bombs from after BDB all the way to Life Spring Infinity.
On Remilia, most of her stuff is straight of dodging, no gimmicks. I've always been good at that, so I don't mind her to be that hard (still hard though, but not the hardest)
Lunatic Byakuren is no just no.
