Seihou - Banshiryuu C67 - Easy 1cc - 182,015,380 (HiranoO)

The hardest category out of the bunch. This shottype's slow movement speed and unique aimshot make her difficult to score effectively with.
She does have her strengths though, such as the aimshot being stronger than her regular shot, much like VIVIT-W. This allows her to accumulate a lot of graze throughout the run in spots where HiranoS or VIVIT-A would not.
Thanks to that, I actually discovered a new strategy that is viable for all shots: grazing the missiles on Yuuta's final. This gives so much graze that it actually outscores the damage bonus, meaning that it is worthwhile even for the high-damage shots like HiranoS. It can give as much as 7000 graze, which is worth 2.1 million.
That said, HiranoO is the lowest scoring of the four shots, but not by that much. Had this run not botched Stage 4 I would have been able to score around 185 million here. That's about the boundary of what would be a good score for me, but I don't really feel like grinding this category anymore for now. Maybe later.
With this, I now have at least decent score runs with all four shots! I'm glad to showcase every single one and what their route looks like. They're all pretty different from each other and that makes it interesting.
