In his last Twitter post of 2019, 42-year-old manga artist Hiro Mashima (Fairy Tail, Edens Zero) thanked the fans' support and wrote, "There will be many surprising announcements next year."

He has been working on two serialization works in Weekly Shonen Magazine, the sci-fi series Edens Zero since July 2018 and the crossover series featuring the characters from his past popular series including Rave and Fairy Tail, HERO'S since October 2019. What is your expectation for the forthcoming announcements in 2020?

"Thank you again for your support this year! There will be many surprising announcements next year. I would appreciate your continued support! Have a happy new year!"

Four hours later, he also posted a "Happy New Year" illustration.
