New anime about 104th Training Corps listed with 13th manga volume on April 9

Japanese retailers Seibunkan, Presepe, and e alamode list Hajime Isayama's 13th Attack on Titan manga volume in a limited-edition bundle with a new original animation DVD on April 9, 2014. According to the store listings, the anime will depict another story about the 104th Training Corps.

The manga had already scheduled the first original anime DVD with its 11th volume, although that DVD was delayed. The first original anime DVD will now ship with the 12th manga volume next month and adapt "Ilse no Techō" (Ilse's Journal), the prologue side story about a survey corps member.

Kodansha Comics is publishing the main Attack on Titan manga in North America, along with Hikaru Suruga and Gan Sunaaku's Attack on Titan: No Regrets and Satoshi Shiki and Ryō Suzukaze's Attack on Titan: Before the Fall spinoff manga. It is also publishing Saki Nakagawa's Attack on Titan: Junior High manga and the Attack on Titan Guidebooks: INSIDE & OUTSIDE . Vertical is publishing Suzukaze's original Attack on Titan: Before the Fall novel series. Both Funimation and Crunchyroll streamed the manga's televsion anime adaptation as it aired in Japan. Funimation will release the series on home video next year.

Update: Illse's affiliation corrected. Thanks, saurers123
