Noir Petal's boards seem to feature a new mechanic that makes for part of the board that is cleared to no longer be safe. Aside from that it's the usual affair of having to avoid enemies, and capture parts of the board that you don't have yet. While her being last in line for the levels to pick from she doesn't seem to have much difficult when it comes to her boards, and I argue they are some of the easiest out of the whole game, DLC included. Aside from that, her pictures are particularly one note, and probably the worst of the bunch as far as I've seen.
