The upcoming fantasy anime adaptation of The Eternal Fool’s Words of Wisdom: A Pawsitively Fantastic Adventure has unveiled a striking new key visual alongside major voice cast additions. Miyu Fujidera has officially joined the cast as Rina, expanding the roster for the highly anticipated series slated to debut in January 2027. Crunchyroll has secured international streaming rights for the title.
Based on the light novel series written by Hifumi and illustrated by Kurihito Muto, which ran from 2015 to 2019 under the Earth Star Novel imprint, the story follows an unconventional premise:
Through the accidental creation of a divine elixir known as Eternity Elixir, Asley gains an immortal body, free from the passage of time. With more time than he could ever need, he devotes himself entirely to research—spending 5,000 years mastering countless spells and magical arts.
