Fairy Tail: 100 Years Quest is a spin-off manga series of the Fairy Tail manga series written and illustrated by Atsuo Ueda. It takes place after the main series and follows the story of Natsu Dragneel, Lucy Heartfilia and Happy as they embark on a new adventure, the 100 Years Quest, a mission for Fairy Tail to conquer which is said to be impossible to complete.
Fairy Tail is a popular manga and anime series created by Hiro Mashima. The manga ran from 2006 to 2017 and the anime adaptation ran from 2009 to 2019. The main series followed the adventures of the Fairy Tail guild, a group of powerful wizards who take on various jobs and missions.
As of my knowledge cutoff, there is no official confirmation of an anime adaptation of the spin-off series, Fairy Tail: 100 Years Quest. The decision to produce an anime adaptation typically depends on the popularity and financial performance of the spin-off series and it’s best to wait for official announcements from the creators or the production company regarding a new Fairy Tail anime series.
The 100 Years Quest: a mission so challenging and hazardous that it has remained unaccomplished for over a century. While countless mages have attempted to take on this grueling objective, their results ended in either overwhelming defeat or worse. Nonetheless, Natsu Dragneel and his friends—Lucy Heartfilia, Gray Fullbuster, Erza Scarlet, and Wendy Marvell, along with the exceeds Happy and Charlés—ambitiously embark on the quest.
A year after the Fairy Tail guild has overcome the diabolical forces of Acnologia and Zeref, Natsu and his team trek into the northern continent of Guiltina, where they seek out the employer of the 100 Years Quest and receive their nearly impossible mission: to seal away the Five Dragon Gods—a group of individuals with such vast power that, if left alone, could cause global devastation. Meanwhile, a spirited new member named Touka is recruited to Fairy Tail. Although her vibrant energy and passionate nature makes her perfect for the guild, there seems to be more to her than meets the eye.
Determined to accomplish their seemingly insurmountable mission, Natsu and his friends begin their treacherous search for the Dragon Gods. However, once encountering a new dark guild named Diabolos, along with the newest recruit of Fairy Tail revealing her true colors, Natsu and his team will find that the 100 Years Quest isn’t the only challenge they face.
