It's static so this seems like a bad option :V Can you even properly shoot the fairy here and get its items?

I don't think the fairy has any awkward angles. If you sit in the middle, you have to tap left-right-left a few times. It's dense, yet, but a really easy pattern. I don't know why people have issues with this. Not to mention that if you really wanted to safespot, why not just hug the corner with border team, which is much easier to find? Not that any of the other shots have any mentionable advantages over border team in survival. Like Remilia and Youmu are more powerful, sure, but in return harder to use with more complicated speeds (Remilia in particular).

I'm quite certain that Reimu's Talismans make short work of all the kedama more easily than Remilia does, because you can just sit somewhere on the screen and they'll do all the work for you. Remilia's bomb is not the most powerful in the game per se. As shown in this thing:



Remilia's bomb is the most powerful against non spells. This is due to her actual bomb not doing any damage, but only when you shoot while the bomb is active. Like, When you bomb and shoot Remilia shoots in the 4 direction of her bomb, and if you sit on a boss, then you do a lot of damage. The reason her bomb is weaker on spell cards is because the armor damage from bombs is calculated for each one of those 4 shots Remilia fires, which means on non spells, where that armor is removed, the damage scaling is removed from 4 sources of damage, not just one. However, at the same time, Yuyuko's large damage and long invincibility frames allow for the last non spell to be taken out as easily, it just takes a bit longer. Rest is like, if you can't dodge 2 bullets, then sure, you'll need another. But generally speaking, most shots need only 1 bomb on average to kill RoD, as you so affectionately call it.

What you say about Iwakasa isn't wrong. It's a very easy spell if you can kill in quickly, which is something Remilia and Youmu can do, so you are right here, even though Yukari isn't that much weaker than either of them, so it would still be an easy capture every time.
Of course, I don't know what sort of crazy strategies you apply when you play, but I guarantee that xu-fu is easier with Border team than with Remi, due to a smaller hitbox. Things like Flying Phoenix or Fujiyama aren't any different in terms of difficulty, though. If you just want to capture Hourai Doll, then I don't think it really matters whether you capture it now when the red arrowheads start or 10 seconds later. It's not a difficult attack at all in the first place for a capture. And if you want to time it down, then obviously Remilia's fat hitbox and fast focused speed are a problem, and not an advantage.
The circle strat on Possessed by Phoenix is impossible and a lot harder than just micro-tapping it, imo. I've never caught it by circling, so to me, Remilia again poses a disadvantage because her focused speed is faster.

The one second to Remilia should be Yuyuko, due to much longer invincibility. Not to mention that IN bombs are very peculiar and you have to use some of them in certain distance so the boss for the best damage. For example Youmu's bomb does best damage if you're just below the boss. So your Reimu deathbomb probably didn't even do close to optimal damage, as you have to be very close so your amulet things can actually hit Mokou.

To be fair, it's true that xu-fu is easy with every shot, but the same can be said for literally every attack Mokou has with the exception of the last non spell. She isn't a difficult boss to no miss at all; and no miss no bomb is something that hinges on only the last non spell. I'm just talking about difficulties between shot types, not that some spells are actually hard, lol. Not to mention that there aren't a lot of things that demand "uber precision", as you put it. But Possessed by Phoenix and Phoenix Tail definitely are not among them. If you were to look into scoring the stage, you would find some things that require precision, but uber precision would still be quite and exaggeration. But you're not there yet. IN extra is a difficult stage to score well in, after all.

Tbh, I never saw why you'd clear something with all shottypes first before moving on to something more difficult, but each to their own.

Well you would be wrong. Why do you think a safespot exists? The fairy is entirely static

I know that the fairy is static but a pattern being static does not automatically make it easier than every pattern that's random or deterministic. Well, it might for some people, but definitely not everyone. At least in my case, I've captured (NMNB'd) everything that IN Extra has except for RoD. And the only ones that I have trouble with (besides the uncaptured RoD) are Imperishable Shooting (which is fully deterministic anyway) and the Death Fairy with any shot other than Border, Netherworld, Youmu, Reimu or Yukari (and I never actually NMNB'd the Death Fairy without utilizing a safespot).

So no, I don't think I am wrong simply because I have more trouble with a static pattern than most of the random patterns in IN Extra. That's like saying that it's wrong to find Yukari's Last Word to be more difficult than Easy Apollo 13.

Again static =/= easier. Death Fairy is very dense, it's easy to screw up the right/left movement you're referring to.

Woo is definitely easier, as far as I'm concerned, it's switching sides periodically. Phoenix Tail might have RNG, but it's still micro where everything is coming from the top (where as Death Fairy is micro with more angles than Tail), but it also has spell practice.
