[QP Shooting - Dangerous!!] Arcade Super 1CC
Cute shmup, this was pretty hard for me -- I was practicing Super difficulty while grinding 99,999 R-points, but hit that number before managing to get the run in Arcade mode, so came back after completing all the achievements. I was mostly just focused on surviving, and not scoring, but did try to combo enough to at least get extra lives. One thing that really helps is the very long invincibility frame window on hit, when you get hit during a hyper you also don't take any damage.
This was using formations (Umbrella, Catapult, Orbit) and Defensive stance. Final score was 36,380,839 but I wasn't really going for that at all.
Credit to Jaimers for a lot of strats, though his video is scoring oriented a lot of his setups also just work to make clearing easier:
