Negima! Magister Negi Magi Volume 0 was released in Japan on August 27, 2011, by Kodansha. This book is part of the series about boy wizard, Negi Springfield, by author, Ken Akamatsu.
Volume 0 is the only bonus volume to be released for the series. It contains a single chapter, one focusing on bonus content and frequently asked questions from fans. In addition, it includes a few extras in the back. The manga is printed in the standard black-and-white.
Due to this not being published and given out as a bonus, it did not need to adhere to Kodansha's policies. The characters in this issue break the fourth-wall to joke and show a nipple, which would never have made it in to the main magazine.
This book was available exclusively in Japan. Select theaters playing the Negima Anime FINAL film would give these books as bonuses to those who purchased tickets, but they were given very limited quantities, 99 copies for each theater.
The areas in theaters were separated into two sections, one featuring Negima and the other Hayate. Each side offered different items.
In addition, stickers were also given to theater patrons. These stickers are a joint piece of merchandise for the Negima Anime FINAL and Hayate the Combat Butler! Heaven Is a Place on Earth films that both aired at the same time. There were six different sticker designs, three featuring a select Negima character in an outfit from Hayate and three featuring a select Hayate character in a Negima outfit. The Negima cast stickers would be available on the Negima-side of the event and the Hayate on the other side.
In addition to the the stickers, a special promo Prism Connect card featuring key art from the movie was available as a bonus for theater patrons.
Note: it is unclear if the stickers and card were only available to those who received volume 0 or if they were available to all patrons. It is also unclear how many quantities were available.
