Encountering a storm on their return from the pirate islands, Col and Myuri are forced to dock at Desarev, one of Winfiel Kingdom's major ports. Though a lively enough town, priests are in short supply thanks to an imminent war with the Church, hence Col's sudden designation as "The Twilight Cardinal," savior of the people! And as if a city's worth of religious problems isn't enough to deal with, suddenly Myuri is demanding to be Col's bride?! Meanwhile, a wool merchant named Ilenia approaches the "couple," confiding that she's the embodiment of a sheep, before asking for their aid with some secret agenda she has cooked up...Though unsure just what to make of this sheep in merchant's clothing, Col and Myuri can't ignore her once she mentions the Moon-Hunting Bear.

After resolving a major source of tension in the Winfiel Kingdom, Col and Myuri have certainly earned their rest. Their respite doesn’t last for very long though because a messenger has come looking for the Twilight Cardinal with news about a conference eighty years in the making. Their destination will be the city of learning and books where there seems to be an uproar surrounding...another wolf girl?!

The young man Col and the daughter of the Wisewolf, Myuri, survived the scripture riots in the port town of Atiph. Col spends intense days being pined for after Myuri tells him about her love. Meanwhile, Heir Hyland commissions them for another next job. In the coming war with the Church's forces, control over the strait between the Kingdom of Winfiel and the mainland will play a crucial role. While Myuri is excited for a new adventure, Col cannot hide his unease after hearing about potential heresy among certain pirates for their faith in the "Black-Mother"!

The young man Col dreams of one day joining the holy clergy and departs on a journey from the bathhouse "The Spice and Wolf Inn," owned by his savior, Lawrence. The Winfiel Kingdom's prince has invited him to help correct the sins of the church. But as his travels begin, Col discovers in his luggage a young girl with a wolf's ears and tail named Myuri who stowed away for the ride! In the past, Col had accompanied the wisewolf Holo and the traveling merchant Lawrence on their own wanderings, eventually growing up alongside their daughter, Myuri as siblings. But as Col prepared to set off, Myuri opposed his departure and so she secretly ran away from home to join him! This is the story of Wolf and Parchment, and the pair's travels that will someday change the world!

Having unraveled the mystery of the ghost ships that visit Raponel, Col and Myuri head back to Rausbourne. The young hopeful priest redoubles his efforts to avoid war breaking out between the Winfiel Kingdom and the Church while Myuri is busy penning her own tale of gallant knighthood. In hopes of further spreading the vernacular translation of the scriptures, they begin looking into the art of printing, which has been banned by the church. Their search for a skilled craftsman soon leads them to a certain fugitive who agrees to help only if they can offer a tale that will make hearts tremble in exchange!

Col has put an end to the battle over textbooks in Aquent and given Rutia a new purpose. With the printing of the vernacular scripture progressing nicely, it's time he prepared for the upcoming ecumenical council, where the clergy of the world will gather. To stand his own in the theological debates that are sure to occur, however, he will need to find as many allies as he can. That's why this is the worst possible time to start hearing rumors of another person claiming to be the Twilight Cardinal. Unfortunately, Col’s constant humility backfires, making it surprisingly hard for him to prove his own identity. What is he to do...?

After defusing another flashpoint in the ongoing fracas between the Winfiel Kingdom and the Church, Col and Myuri are more than ready to take a breather. Of course, the world has other plans for the infmaous Twilight Cardinal. As the two of them leisurely make their way to a certain monastery, they stumble upon a fallen squire who is up in arms the moment he finds out who they are. With the world's strongest holy order of knights on the brink of dissolution and Col apparently to blame, there's no time to waste!
