Finally captured Hourai "Fuyijiwara Volcano". It was even easy o.o
Now I just need Posses by Phoenix (damned 2nd phase!) and Hourai Doll for all extra cards captured.
Fujiwara Volcano isn't too hard if you know how to do it. But if you die, you respawn at the center of the screen, which is VERY bad, because makes it really hard to misdirect her attacks properly.
Possessed by Phoenix : The second phase is much easier if you start from one of the top corners, because it lets you stream at the bottom of the screen when you run out of space moving vertically. Move unfocused when you get near the bottom wall to create a gap, wait a bit for the bullets to aim at you, then move to the sides.
Hourai Doll : Tap up, tap right, tap down, tap left. Repeat. When she starts shooting yellow bullets, and the aimed arrows later on, continue moving in a circle, but take more space so you can dodge (move in a bigger circle).
