At the risk of necro posting, I'll say that this manga is amazing!
After seeing the first chapter, I noticed that the drawings were different from many other mangas and was like "O_O! Gotta read this!". Plus the idea seems to be pretty cool.
I was pretty sad when Youchi (?) turned out to be a guy.......D:
I enjoyed the part when Jeanne d'Arc appeared. Those flames made me instantly remember about her being burned.....O.O!
Also LOL @ the way they make fun of Hitler xD.
