I thought I recognized the style. Pushing aside the rather obvious allegories etcetera etcetera, the art is of a true hand-drawn nature and its imperfections lend well to its expression. Shiki's works are not typically light reading, but they're entertaining in their own right and thought-provoking for some demographics especially. If you're an older teen or young adult, you'll probably enjoy this quite a bit as a dramatic action series with a deeper plot than a more exciting shounen.
