As the Overlord II TV anime ended, the anime’s official website has updated to announce Overlord III. Much like the original anime, as well as Overlord II, this new series will also be a TV anime. They also revealed a new CM to formally announce the new anime and its July 2018 premiere.
Meanwhile, Overlord anime’s official twitter page also made its own announcements. According to a new tweet, Takahiro Sakurai will voice Gilkunif, while Takaya Hashi will voice Fulder. Fans will get to know these two new characters as Overlord III airs this summer 2018.
