Ludwig Revolution is amongst one of the more odd mangas I've read. I did enjoy the spin-offs of many a beloved Grimm fairytale characters (Blanche and Sleeping Beauty were particularly interesting).

The 'dashing' prince bit is amusing, and the plot twists are fun to follow. Now an amazing story, but if you have time to kill on something that's a bit of a light hearted twisted tale Ludwig's adventures isn't too bad a choice.
