Some interesting plans are being put together for the Japanese home video release of Attack on Titan. The first volume, shipping July 17th, will feature a 64 page protoype manga that author Hajime Isayama created at age 19. It also features sleeve case drawn by character designer/animator Kyoji Asano, illustrated card by Flowers of Evil's Shuzo Oshimi, and 12-page color booklet.
Then, volumes 3 and 6 will feature mini-visual novels by Steins;Gate's Nitroplus, with Isayama supervising and Namaniku ATK providing character art.
Volume three, due September 18th, will feature anime writer Hiroshi Seko's Mikasa story "Lost in a Cruel World" and the prologue to Nitroplus writer Gan Saaku's Levi and Erwin story "A Choice With No Regrets."
The latter is picked up in December 18th's volume six, along with Jin Haganeya's story about the characters and a second Hiroshi Seko story about Annie.
