Staff for the Yuukyuu no Gusha Asley no, Kenja no Susume (The Eternal Fool’s Words of Wisdom/悠久の愚者アズリーの、賢者のすゝめ ) TV anime have revealed the show’s main visual and confirmed that Fujidera Minori will join the cast as Rina.
Ounishi Keisuke is directing the anime at Studio Elle, and the anime will premiere in January 2027. The anime will star Toyonaga Toshiyuki as Asley and Hikasa Youko as Pochi.
The show is based on the Yuukyuu no Gusha Asley no, Kenja no Susume light novel series by Hifumi and Mutou Kurihito. Both Mutou and Araki Fuh, the artist behind the manga adaptation, have drawn illustrations to celebrate the anime adaptation.
Hifumi started the original story in January 2015 on the Shousetsuka ni Narou website, and Taibundo Publishing released the first novel in print, with illustrations by Mutou, in September 2015. The 14th and final novel was released in December 2019.
The novel series was adapted into a manga by Ariki in April 2017 on Earth Star Entertainment’s Comic Earth Star website. Earth Star Entertainment published the manga’s first tankoubon volume in November 2017, and the manga’s 13th volume in February 2026.
J-Novel Club releases the manga adaptation in English under the name The Eternal Fool’s Words of Wisdom: A Pawsitively Fantastic Adventure, and it describes the manga story below:
“A couple thousand years of solitude would wear down any young man—that is, anyone except Asley, an eternally youthful and eternally foolish sorcerer. After all, he has man’s best friend…er, familiar, to keep him company. When his Level 100 canine companion Pochi demands that he get some fresh air for the first time in two centuries, Asley sets out to reintegrate into society and test his magic mettle. His mission? Dropping several unglamorous titles from his repertoire and restoring his good (okay, decent) name.
A brand-new world and fresh adventures await Asley after his many years of hermitage. Perhaps he’ll lend Pochi a hand to place first in the mysterious Familiar Feud. Or maybe he’ll lose all vestiges of dignity and turn tail. Whichever comes first! No matter what, Asley has great evil to fight, a big world to save, and even a little growing up to do…that is, if he can endure Pochi’s “friendly advice” along the way!”
