With the Fate/Stay night series as popular as it is, and seeing how most of its spin-offs go on to great success, it was only a matter of time before the Fate/Extra series got an anime series of its own.
Fate/Extra: The Last Encore is set to premiere in Japan on January 27, so it has released a teaser featuring one of the series' Servants, the Saber Class, Gawain:
Takahiro Mizushima is returning to play Gawain, while the confirmed cast list includes Atsushi Abe as the main character Hakuno Kishinami, Sakura Tange as the Saber class servant Nero, Urara Takano as the Rider class servant Francis Drake, Kousuke Toriumi as the Archer class servant Robin Hood, Ai Nonaka as the Caster class servant Nursery Rhyme (like Mother Goose), and Kunihiko Yasui as the Berserker class Li Shuwen (rather than the Assassin class he held in the video game series).
Studio Shaft is adapting the series with Akiyuki Simbo (Puella Magi Madoka Magica) serving as the chief director with Yukihiro Miyamoto (Puella Magi Madoka Magica) serving as series director. Masaaki Takiyama (Tokyo ESP) is designing the characters based on Rco Wada's original designs, and original Fate/stay night creator Kinoko Nasu and Satoru Kousaki of The Melancholy of Haruhi Suzimiya are composing the music for the series.
If you're curious for more of the Fate series, Fate/Stay night, Fate/Stay night: Unlimited Blade Works, Fate/Zero, and Fate/Apocrypha are currently available to stream on various streaming platforms like Hulu, Netflix, and Crunchyroll.
For those unfamiliar with Fate/Extra, it's a spin-off of the Fate/stay night visual novel series from Type-Moon, written by Yuichiro Higashide and illustrated by Ototsugu Konoe. The video game series follows an amnesiac main character who wakes up in a virtual world and must fight others in a tournament where the winner is granted one wish. The main character is then given a Servant, a popular hero in history who has been summoned, in order to fight enemies and eventually strive for the Holy Grail and to figure out their own identity.
The series started as a dungeon crawling RPG developed by Type-Moon and Image Epoch for the PlayStation Portable system in Japan in 2010 and was later licensed for a release in the United States by Aksys Games.
