Whether or not you actually execute the bug is irrelevant, because transitions and events don't add to the stage time, it merely helps with real-time. It helps to mash on the start button, but that doesn't always do it because the timing is a bit precise. You must destroy the save on the card and start fresh to remove it if one is there.
Unfortunately, there is no way to remove a 'Clear!' if it is already there. You can play through a Musou Mode and still not get a 'Clear!', but you must not save after the final stage. To attain the fastest route on Musou Mode, you must play a Musou that does not have a 'Clear!' under it.Three difficulties are available, Easy, Normal, and Hard.
