As you can see, I'm nowhere near 1cc on Hard (frankly, I didn't even try it on Easy or Normal either). Which brings me to certain points I believe need to be re-made.
Playing without continues does not equal going for 1cc (see above).
Mapping the sword attack onto some other button than fire helps.

(I played all the way through on Normal as Isa, then Kachi using the deafult setup; Stage Select made clear to me that tapping fire button to perform slash hinders my performance.)
