Negima! Magister Negi Magi Vol. 27 (Limited Edition) was released in Japan on September 28, 2009, by Kodansha. It was a limited edition release of the manga containing an OAD episode of a new animated season of the series.
The contents are encased in a thick box, sporting the logo and characters. Inside is of course the manga, but the cover varies from the original and features a similar, but different alternative design, this particular one with shirtless Jack Rakan. This specific cover was only available in this box set.
Also included is a DVD of episode 1 of the Mahō Sensei Negima: Mō Hitotsu no Sekai/Magical Teacher Negima! ~Another World~ OAD series, a new animated season by Studio Shaft. This set includes a box designed to hold the Another World DVD's; though the series is only 4 episodes (if you don't count the Yue Special), the box can hold 5 DVD's.
The last item included is a special Kaede Nagase pactio card.
The DVD is Region 2, meaning it may not play on many DVD players. The box was only released in Japan.
