I'm very surprised no one has reviewed this manga yet. It was really a fascinating read. Although it starts out comically, with the siblings switching genders for relatively frivolous reasons, it really shows the far-reaching consequences of their actions. The main character is intelligent, energetic, and naive but at the same time able to masquerade quite believably as a man. So although those adjectives sound like she would be your typical shoujo heroine, she is really something unique and quite a fascinating character. Another thing I really liked is that although there was a great deal of drama and themain character was often in distress, it was over situations that you don't often see in a normal shoujo and I didn't have the feeling that problems were dragged out to make the story longer. The art wasn't anything special, but the characters were attractive and to my totally untrained eye appeared to be entirely in period dress, which was fun. My only complaint is that I would have liked to see an epilogue, but other than that the story was immensely satisfying and I would highly recommend it to anyone interested in historical or gender-bending shoujo.
