The 100-Year Quest is a sequel to the main Fairy Tail series, written by Hiro Mashima and illustrated by Atsuo Ueda. It follows the adventures of Natsu Dragneel, Lucy Heartfilia, and their guildmates after they complete the original series’ events.

The story begins with Natsu and his team (Lucy, Erza, Gray, Wendy, Happy, and Carla) embarking on the infamous 100-Year Quest, a mission so dangerous that no guild member in history has succeeded in completing it for a century. This quest leads them to the continent of Guiltina, where they are tasked with sealing the Five Dragon Gods, immensely powerful dragons whose existence poses a threat to the world.
