Premieres sometime in 2025. The new PV is here. Check out the ANN article for additional information. Synopsis from AniList:
Monica Everett, the Silent Witch, is the world’s only practitioner of Voiceless Magic, a veritable heroine who single-handedly fended off the Black Dragon of legend. However, the young prodigy is actually…super-duper shy! Yup, turns out she only learned Voiceless Magic to avoid speaking in public. Ignorant of this, the Seven Sages have placed her on a top-secret mission to guard the Second Prince. Can Monica keep it together as she contends with both social interaction and the evils targeting the young royal?
When I was reading a Light Novel it has sucked me in so hard that I binged read the MTL of the web novel. I am looking forward to the adaptation.
