Remi Lunatic.
She isn't easy...
1st non-card
You have to unfocus at times to swerve around things.
Do NOT try to go between a metal fatigue and a bubble, or it's recipe for death. Move around them instead
1st card - Young Demon Lord
Generally, you want to stay in the largest gap below Remi.
When the bubbles get near bottom, you first read a path (it may involve lots of horizontal), then go through asap.
The laser hitbox disappear faster than they look, so use it to your advantage
2nd non-card
Stream is easy.
Non-stream: (you can shot gun first), stay bottom of screen and 2 characters right or left of Remi to dodge.
2nd card - Mountain of 1000 Needles
Shotgun Remi in beginning.
Beware of knifes, you have to read them well in advance to move away from them.
If you aren't comfortable moving large distances, I recommend staying in the center near bottom so that you don't miss Remi often and time out due to her moving to the other side of the screen.
3rd non-card
Don't auto-collect. This is the easiest attack.
3rd card - Vampire Illusion
You stand still in the center slightly up from the bottom of screen. This gives you widest attack range.
There are basically 3 different types of waves, which you will recognize (kind of) when you play a lot.
Type A requires you to stay and make minimal movement, most of the wave misses you.
Type B requires you to move farther up and dodge bullets from below and sides.
Type C is a wall, which requires you to either move around it, or micrododge at the bottom of screen
You move around if you are near the edge (i.e. right end) of the wall.
Otherwise, you have to micrododge (which isn't that hard if you are more on the "left" side of the wall).
Sometimes, it gets shitty with Type B and Type C following each other, and that's where you probably should bomb since you need to dodge Type C at the bottom, but that's precisely where it is very hard to dodge Type B
4th non-card
Wave 1: you dodge, look for the widest gap, but be careful when reading, because the bullets aren't entirely vertical
Wave 2: you tap half a bubble distance right after you hear every firing sound
Wave 3: stream, very very easy
4th card - Scarlet Meister
Watch this if you intend to capture:
http://www.youtube.com/watch?v=LgPffmr2pbsI have 0/550 on it. I can't last beyond the 2nd wave even if I try really hard.
5th card - Scarlet Gensokyo
You have to be able to pass the first bubbles 100% of the time without clipping. It's not that hard.
There are 4 waves: 1 "hard" wave (the most bubbles), and 3 "easy" waves
It just cycles through those waves that sequence until the end.
Depending on your character, there is a time where you shouldn't bomb due to having a large bubble wave right after.
Figure out the correct time to bomb so that you can avoid all the hard waves (the one with shit loads of bubbles)
OR
Learn to dodge. There is a certain kind of pattern that the stationary bullets start to move in all waves.
I don't know how to explain, but eventually you will figure out how to survive the hard wave.
The key is recognize which directions the 5 bullets right beside you are moving, then react instinctively.
After the hard wave goes, it gets much easier for other 3 bubble waves, where you can just read and dodge.
When the hard wave comes again, and you actually want to dodge it with all the random bullets still on the screen,
you stay somewhat away from directly below Remi, so you have room to micrododge everything at the same time.
Once in a while, a wall will form (from residual bullets in the last easy wave) to wall you while you are in the hard wave.
This killed GIL before and is basically almost 100% impossible, so you should bomb.
Also, here a replay (the only replay I have of stage 6, in fact):
