*Specials of the Prison School manga promoting the anime adaptation of the series.*
Hanamura's manga charts how the anime Prison School came together under the helm of director "Crazy Boy" Tsutomu Mizushima, and shows the production committee's raucous discussions over important details like the color of Meiko's panties or the sound effects in Gakuto's defecation scene. The anime's main voice actors—Hiroshi Kamiya, Katsuyuki Konishi, Kenichi Suzumura, Daisuke Namikawa, and Kazuyuki Okitsu—also play supporting roles.
