Fairy Tail manga creator Hiro Mashima revealed on his Twitter account on Monday that he is working on a "secret" project. He said that he is becoming "a little confused" due to simultaneously working on his new manga, Fairy Tail, and an unnamed project, which is "still a secret." He also noted that "ideas emerge one after another" for his new manga. North American publisher Kodansha Comics revealed sketches for Mashima's upcoming manga in April. The company did not confirm a simultaneous publication, but teased, "Japan … America … Europe… The world is waiting … Eleven months have passed since the finale of Fairy Tail. Now a new adventure awaits. On June 27, 2018 the new series by Hiro Mashima begins!" The new manga series in Kodansha's Weekly Shōnen Magazine in this year's 30th issue, which will ship on June 27. Mashima teased details about the new series in January, stating that "it will be a new form of fantasy." He added that "Plue will make an appearance" in the new manga. Mashima also announced in April that a Fairy Tail sequel manga is in the works in the form of a spinoff manga. In addition, he announced that he is working on another Fairy Tail spinoff manga. Mashima did not specify if he will be the one drawing either of those two manga. The Fairy Tail manga launched in 2006 and ended last July. The manga has inspired two television anime, two anime films, several original video animeprojects, and spinoff manga. Kodansha Comics publishes the original manga and a number of its spinoffs in North America. The television anime's "final season" will premiere this fall. Mashima also created the manga Rave Master, which ran for 35 volumes and inspired a 51-episode anime adaption of the same name.
