The Easygoing Territory Defense by the Optimistic Lord: Production Magic Turns a Nameless Village into the Strongest Fortified City TV anime will star Yumi Uchiyama, M.A.O, and Mariya Ise as protagonist Van, Van’s maid Till, and the loyal Khamsin, respectively. It was also announced that the anime will premiere in 2026.
Easygoing Territory Defense by the Optimistic Lord is based on the light novels written by Sou Akaike and illustrated by Kururi, which are published under the Overlap Novels label. Seven Seas Entertainment describes the premise as:
Van, fourth son of a marquis, is just a toddler when he realizes he’s been reincarnated. Thanks to his literal lifetime of knowledge, he’s raised as a child prodigy—until his production magic manifests, and it’s the last thing his snooty mage family wants to see! His disappointed father banishes him to a podunk town on the verge of collapse, yet Van can only see the place’s potential. Can our hero’s bastion of battlements build a better life than battle magic ever could?!
The story started as a Shosetsuka ni Naro web novel in 2020. There is a manga as well.
