I watched all of Midori No Hibi, it was pretty cool. Definantly a unique concept. I would like to check out the Manga soon enough.
By the way, if I may ask. Do you get your username from Mahou Sensei Negima?
I've read some of it, and its great. Can't wait to view it when it starts airing, which should be around January sometime, I believe.
Also, since you're in Japan, may I also ask another question?
Does Hokuto No Ken still have a large following over there?
Over here it has a small fanbase, and I am probably at the top of that (Considering I spent over a thousand dollers to import the Super Premium Box Set), but I have heard that it is still very popular. Even Gackt is still a huge fan (lucky guy got to do voice work for Shin Hokuto No Ken).
