According to the official website, the Anime adaptation of Nanatsu no Taizai (七つの大罪, The 7 Deadly Sins) was announced. Nanatsu no Taizai is originally a multimedia project from Hobby Japan, as well as Orchid Seed who mainly responsible for the figure production. The project revolves around seven female demons who represent the seven sins. What an old, rusty and cliche story is will be, and it “somehow” reminds me of Queen’s Blade which was brought to the screen by the same folks. It could be a meaningless story filled with loads of fan services while the official website does emphasize that it won’t be adult only. You can read more about the character design on ANN.
