While the premiere date is yet to be confirmed, both a celebratory visual and PV by original author Hiromaya Hiroshi have been released.
Fate/kaleid liner Prisma Illya began as a manga in 2007, transforming Illyasviel von Einzbern (first featured in Fate/stay night ) into a magical girl. With the Holy Grail War having already been prevented, Illya grows up in relative peace, but soon finds herself on a mission to collect the seven Class Cards under the supervision of sorceress Tohsaka Rin.
The TV anime adaptation first aired in 2013, and went on to receive four seasons altogether. Other works include a movie titled Fate/kaleid liner Prisma Illya: Oath Under Snow, and an OVA titled Prisma Phantasm, as well as a popular game and series of novelisations.
