We learned just about ten days ago that the Juuni Taisen property got the nod for an anime adaptation and now some new details have arrived. The novel from writer NisiOisin and artist Hikaru Nakamura is a prequel to the Oogiri work and it came out in 2015. The promo confirms that Naoto Hosoda will be directing it based on the series composition by Sadayuki Murai. Chikashi Kadekaru is handling the character designs for it and we learned previously that Graphicina will be handling the animation production.
The Japanese cast includes Nobuhiko Okamoto on board to voice the character of Usagi.
Plot concept : The story is about twelve special fighters who battle against each other in order to have their wish come true no matter what. These fighters represent the twelve Chinese Zodiac.
