Natsu vs. Mavis is the eighth OVA for the Fairy Tail series by Hiro Mashima, and the second for the 2014 anime series. It was bundled along with the Special Edition of Volume 58 of the Manga, which was released on November 17, 2016. After Erza recruits Natsu to assist Mavis by allowing her to enjoy the qualities of a hot bath, Team Natsu and Juvia take up Warrod's request to look for a hidden treasure buried by the First Master herself 100 years ago, although the task becomes much harder than it was initially let on.
