Alright, I'm back. Again.
Firstly there's Counter Clock. I don't get to it often so I can't really learn it.
And secondly there's Yuyuko. Just...Yuyuko.
Can't help you with the little Scarlet sister, but...
(All tips/advice here is assuming Normal difficulty.)
Yuyu nonspell 1:
After she fires the first wave, move to the right or left a bit so the rice bullets don't get all wall-y on you. Then just weave as best you can and go from there for the big wave after the two solitary ones.
Lost Soul's Village
I'd say there's not much to say but learn to read the angles of the bullets more, and remember the laser swings slightly farther each round, so you'll want to end it quickly if you can. Stay under her as long as you can, then hightail it when the laser gets too close or the bullets get to be too much of an issue.
Yuyu Nonspell 2
Here, you'll want to start shooting in the middle so you hit her and do more damage. After a few seconds(Right before the bubble bullets start up) you should move far to one side(I go left.) and slowly stream them. Careful of the purple bullets though. They can clump sometimes and get annoying til you pass the little wall of em that forms towards the beginning.
Law of Mortality
This one's a PAIN... You need to weave through the butterflies and stream the bubbles. Switch directions each time the bigger gap between bubbles shows up, or you'll probably run outt of room and have to bomb.
Yuyu Nonspell 3
This one's not so bad. Just pay attention, and be careful when weaving through the knives when they start gunning for you. After a couple waves of em try to take you out, if you're careful they won't aim directly at you due to your movements to avoid the bubbles.
Flowery Soul
Start up near Yuyuko. Slowly move down so the butterfly burst ghost things aim up high, then dart down. Then, just move from middle-side-middle-other side-middle-side-etc. after each burst. Stay low so you have more room to dodge the blue bullets. Don't try to rush it, and this can be relatively simple. Probably her easiest spell card, IMO.
Yuyu Nonspell 4
Here, the trick is that when they're fired, only the dark blue arrows are aimed at you, the others are around you. Just do small movements to avoid the blue arrows and be careful of the butterflies.
Repository of Hirokawa
I can't help you with this one, as I've never been able to fully figure it out. I believe it involves starting out on one side and streaming the aimed butterflies slowly as you move the other way, then doing a dash to the edge when you get close to the other end, followed by weaving through the remnants of other streams as you work your way back, but I'm not sure.
Sumizome Perfect Blossom
All sorts of stuff going on here. This one's really got little trickery to it besides the aimed nature of the butterfly bullets. Hard to deal with so much going on at once, but as long as you don't get yourself walled off you'll be fine.
Resurrection Butterfly
Really, if you're going for a first 1cc, bomb Yuyuko into the ground. It's not worth the aggravation to try and cap this thing normally. Anything you even THINK will come close to hitting you, bomb it. If you want a capture, just paty careful attention to the red butterfly bullets, as they're aimed either close to you or right at you. Very hard on higher levels, and I think other stuff gets added above Normal, but I don't know.
Phew. Should help a little with whatever you may be having issue with from Yuyuko, hm? Good luck!
