DS, any scene of level 7 except 7-6
7-1
First phase: Load and rush. She'll never get any real shots out and if she does read them. Not a biggy.
Second phase: Stay near her and dodge the lasers. The laser gets wonky at the bottom but is predictable near Shou
Third phase: Use vert camera. The basis of the lasers and gloving balls is the same as in first phase just that it's harder to read. When loaded, clear everything she's shooting and back down.
7-2
A bit to Nazrin's left is a strange vertical space where she rarely drops her bullets. Of course she moves so most of the time some other bullets get in the way but try to keep to her left and quite close by.
7-3
A bit harder one. Attempt to lure Shou's afterburner somewhere it will have least damage. Clear as many shots as possible while shooting Shou. Try to memorize the angle of the closest afterburner stream to help positioning.
7-4
Nothing special here other than it's a puzzle scene. Keep loading constantly and dodge everything that comes. Clear the lasers, rinse and repeat. The last shot is especially hard; if you don't keep loading all the time, you won't make it.
7-5
Fun puzzle. Shou will only shoot to the squares vertical and horizontal to her, so whenever she moves you must have camera loaded and ready to take a photo and clear lasers to escape into a square not in her line of fire. After second photo she will start shooting blue orbs all around, which all you can do about is dodge. Don't wait close to her for her to finish shooting but at a corner far away. For example you pick the square bottom-left of her so you wait at the corner leading to two squares beneath her, after which you will wait at the corner leading to the square two to her right of the square she moved to. Don't use the bottom three squares. Also watch out for taking a picture too early and escaping or she'll follow you into the square you just escaped.
7-7
Haven't passed this one yet but my tactic so far is to keep an eye on the wave coming from the left and dodge them around the middle and when I see the second wave coming from right, I'll just follow the path created by it while dodging lasers.
P.S. Long time lurker reporting in.
I need help on 3-4 of DS.
Furienify has made a video shoving how to do it.
