Just as author Hiro Mashima's Fairy Tail manga received an anime adaptation, its sequel will also be receiving the same treatment. Titled Fairy Tail: 100 Years Quest, the manga follow-up began in July 2018, and the confirmation of an anime series landed in July 2021. Since then, Fairy Tail: 100 Years Quest anime release details have been vague, with hints at an announcement in late 2023 and a possible 2024 release date.
