People who die easily due to the difficulty of the medium- and top row levels of Arrange Mode will end up in the bottom row, which are just the original Levels and isn't on Professional difficulty. Good thing too if you just wanna finish a run quickly because theres no second playthrough required to get the bracelet. The only Levels that are required are Stage 1 (Professional) and Stage 7 (Professional mixed with arranged chests). If you manage to reach alternate Stage 5 and clear it with bronze armor, you can also skip Stage 6 completely, though thats another story.
