I know there are 11 volumes, but exactly how many chapters are there to this series so far?

It's kinda strange... I really have no idea, I think about 40-41 chapters. I know that we're up to volume 12, chapter 2 right now. The manga never really numbered its chapters the way they're usually numbered.

meh, i saw the anime, can anybody tell me what chapter they start splittin off from the manga?

"Hip-hop was set out in the dark. They used to do it out in the park"

What is this Argentine Special? Does anyone know if it will be on Tank when released? Or is it just a non-canon chapter which was there ... just because?
