Now I've made it to Utsuho with two different shot types. I don't think ReimuB is working out - Ghost Wheels, of all things, is destroying my resources. Not sure to continue or not.
I believe the wheels in ghost wheels count as bullets, so if you plant one on top of Orin, you might be able to skip it with 2 bombs, similar to MarisaB. I'm not 100% sure though.
Watched your replay too, here are some things:
Stage 1:
-Stream straight down the middle before Kisume and you don't need to run around for power and can end her card quicker.
-There's a much easier way of doing Kisume's first card. Make Kisume move to the left/right three times, cross under her to the middle, then stay constantly under her as you make her move towards the opposite direction you lured her in. You should only need to dodge a few bullets. It's a very consistent method for me, but if you're fine with what you're doing, then go for it.
-I recommend maxing the communication gauge at the very last wave of the stage, and just streaming the whole thing to a corner. I find it's much easier to get caught off guard otherwise. Again, see the last sentence of the previous point.
Stage 3:
-The whole bit with the lasers before boss Yuugi is almost trivialized by sitting in a corner, or very close to it. I use the left one because I stream from the right to get the red fairies. I would recommend bombing it with a lot of other characters, but with ReimuB's bomb, the spirits it spawns homes in on Yuugi, which means you get pretty much no power from it. Sucks.
-Yuugi's second non-card is static based on her position. There is something close to a safespot the left of Yuugi's "enemy" marker. You'll just need to adjust based on Yuugi's position, and dodge the blue lasers accordingly. The red lasers will never hit you there though.
-Yuugi's last non-card can be easily done by dodging the initial wave from the center, moving upwards to avoid the clusters from the side, and moving to the left/right and camping in the last third/fourth of the screen, making only minimal dodges.
-You handled Ooe beautifully, despite the one death. I'm never confident enough to make some of the dodges you did.
Stage 4:
-You should never die to the red lasers before midboss Orin. If you start from the center and stream to the left/right when the red lasers come, you'll always kill the orbs that spawn the lasers on that side, and you won't have to dodge anything. This will only work above a certain power threshold though. It definitely doesn't work at 0 power.
-I'm going to assume the bomb at the beginning of the green amulet section was specific to this run, but if it wasn't, just know that the green amulets are static.
-The red lasers in the section after the green amulets can be handled in the same way as the part before midboss Orin, but the green amulets linger on the screen, making dodging the first wave of red lasers difficult. The same general strategy applies though, just watch out for the green amulets.
-Christ the way you dodged Terrifying Hypnotism was magical. How in the world do you do that? Same with Pandemonium.
Stage 5:
-I really don't recommend immediately bombing midboss Orin's first non-spell. You will spend a lot more time in popcorn hell if you do. If you let it go for a while, you won't even need to bomb once during it.
-Yeah you should learn the cheese method for the second non-spell
-Don't sit on top of Orin while bombing during her final card. She won't fire the popcorn bullets if you do, and you'll miss out on some bomb damage.
Stage 6:
-I would say to learn how to do the purple streaming section, but I never bothered to learn either, so I'll keep my mouth shut.
-If you have the power as ReimuB, always plant the bomb on top of Orin right as the card starts. You'll deal a ton of damage.
-And like Nindella said, the Bowap fairies are static. If you want to bomb one, bomb the first one, as I believe its pattern is slightly harder than the second.
-I find that doing Okuu's non-spells where she flies around the screen (second and fourth I believe?) to be easier if I'm closer to the middleish of the screen. I can't remember when I last legitimately died to them. Your mileage may vary.
You're a much better player than I am, and I managed to barely scrape through a 1cc with ReimuB, so you can definitely do it. If you just learn to trivialize a few more things, then you can get this 1cc easy. Okuu past her first card isn't terribly hard. You got this!
