Third Zero no Tsukaima TV Anime Series Announced
A flyer inserted into newly published books from MF Busho J, the light novel imprint owned by the production company Media Factory, has announced that a third television anime series has been greenlit for the Zero no Tsukaima fantasy comedy franchise. The announcement was made in conjunction with the 13th volume of the light novels, which are written by Noboru Yamaguchi and illustrated by Eiji Usatsuka. The 13th volume, Seikoku no World Door, will be released on December 20.
I hope they make up for the mediocre second season and it’s more than cheesy ending.
