As an anime television series that falls under alternate history genre, I find the animation quite good, especially that war is also playing a big role on the plot, Also, let's not forget that the anime is not adapted from any outside sources, not from a manga nor light novel so props to the studio for this wonderful work.
Would Izetta: The Last Witch get another season? I definitely believe that the anime would get a season two. Izetta's vision is not only to bring peace within Eylstadt but to bring peace to the whole world, there's also a lot of mystery to cover which includes the first white witch and her grandmother's. To be honest, I already pre-ordered one figure of Izetta at 1999.co.jp to support and push the franchise. Hopefully my purchase would be one of the millions to support Shuumatsu no Izetta's second season.
