After three years of anticipation, your favorite light novel “A Tale of the Secret Saint” is finally getting its anime adaptation! Announced on March 6, 2025, this beloved series following Fia’s attempts to hide her Great Saint powers has already captivated millions with 2.7 million copies in circulation. Between its successful manga adaptation, spin-off series, and back-to-back second-place rankings in Kono Light Novel ga Sugoi!, it’s no wonder fans can’t contain their excitement. There’s plenty more magic behind this announcement’s curtain.

Three years of anticipation have finally paid off for light novel fans as “A Tale of the Secret Saint” scores its much-awaited anime adaptation, announced on March 6, 2025. You’d be hard-pressed to find a more deserving series, considering its impressive track record of 2.7 million copies in circulation and back-to-back second-place rankings in the prestigious Kono Light Novel ga Sugoi! guidebook.
If you’ve been following the series since its humble beginnings on Shōsetsuka ni Narō in January 2019, you’ll know it’s come a long way. The story, penned by Touya, quickly caught fire and landed a proper light novel publication with Earth Star Entertainment just months later.
Now, with ten volumes under its belt and stunning illustrations by chibi, it’s clear why fans couldn’t contain their excitement at the announcement. The series follows the compelling journey of a young woman who must carefully navigate her path while concealing that she possesses lost magic of myths.
You might’ve already discovered the manga adaptation, which has been running in Comic Earth Star since December 2019. With eleven volumes illustrated by Mahito Aobe and an English release by Seven Seas Entertainment, the series has proven it’s got staying power.
Speaking of international appeal, you’ll be pleased to know that both the main series and its spin-off, “A Tale of the Secret Saint ZERO,” are available in English.
The story’s premise – following Fia, a reincarnated Great Saint trying to keep her powers under wraps for a quiet life – has clearly struck a chord with readers. The spin-off series has already spawned five volumes and its own manga adaptation, illustrated by Shiina, with two collected volumes as of September 2024.
Let’s be honest – with these kinds of numbers and this level of cross-media success, an anime adaptation was practically inevitable. Still, that hasn’t stopped fans from expressing their utter disbelief and joy at the announcement.
Given the series’ consistent quality and growing popularity, you can bet this adaptation will be one to watch when it finally hits screens.
