I could understand how this could not be great for accessibility, but basically when the "Hold to Attack" option is enabled, Hattori's will do a full hit combo before letting you charge the dash cut. I like using the "Hold to Attack" for various weapons, but having to turn it off just for Hattori's and then back on again for any other weapon is a bit frustrating.

They could make the dash active by pressing the button twice in a quick row
