The Granblue Fantasy series is about to expand with a series of shorts called Guraburu!, and the new Granblue Fantasy spin-off officially has a start date. Based on the four-panel gag manga series illustrated by Hitomozi Kiku, the shorts kick off on Tokyo MX and BS11 in Japan on October 8.
Kenshiro Morii (BanG Dream! Girls Band Party! Pico) is directing the Granblue Fantasy spin-off, with manga author Kiku on board as the series composition writer. The series is being co-produced by DMM.futureworks and W-Toon Studio (UMAYON).
The Granblue Fantasy spin-off will also see all the cast members from Granblue Fantasy the Animation returning to reprise their roles, including Rie Kugimiya, Nao Toyama, Miyuki Sawashiro, Hiroaki Hirata, Yukari Tamura, Kazuhiro Yamaji, Rie Tanaka, and Emiri Kato.
Here’s a teaser from April:
Crunchyroll streamed the Granblue Fantasy anime as it aired. Here’s the official description:
This is a world of the skies, where many islands drift in the sky. A boy named Gran and a speaking winged lizard named Vyrn lived in Zinkenstill, an island which yields mysteries. One day, they come across a girl named Lyria. Lyria had escaped from the Erste Empire, a military government that is trying to rule over this world using powerful military prowess. Gran and Lyria, in order to escape from the Empire, head out into the vast skies, holding the letter Gran’s father left behind – which said, “I will be waiting at Estalucia, Island of the Astrals”
