Plot
Fifteen years have passed since Tote Col initally set out on his quest to become a priest. Even after all that time has passed, his goal of reforming the Church has never faded. While his help at the Spice and Wolf bathhouse will be sorely missed, Col leaves Nyohhira behind and his beloved little sister, Myuri, along with it.

Or at least, that is what he thinks: not even a few minutes into his travels does trouble start in the form of a half-wolf, half-human girl. Myuri managed to stow herself away on the boat Col's using, and she is dead set on coming with him. Though he wants her to return home, he eventually relents, allowing the straightfoward wolf girl to aid him in future adventures.

Light Novels
There are six light novels.

Manga
A manga adaptation of the light novels began in 2019. The art was drawn by Hidori.
