This is a very interesting manga to read. It not only has so much action, but it also educates you. I'm hooked and can't wait for the next chapter to post. If this is/was made into an anime, then I would not be surprised. It is just that good...

This was by far one of the best mangas I have ever read. This was truly a work of art. The illustrations were also amazing. Hopefully an anime and a movie will be made from this because it was just that good... I wished I had some popcorn while I was reading though...
