Wolf & Parchment: New Theory Spice & Wolf, Vol. 10 (light novel)

In the course of exposing the imposter posing as the Twilight Cardinal in Estadt, Col has finally resolved himself to bear the full weight of his title. And supporting him through every trial and tribulation is none other than Myuri, the proud Saint of the Sun. As they finalize their preparations for the ecumenical council, the two receive troubling news that Irenia, a subordinate of Abe and the incarnation of a sheep, has been imprisoned. And to make matters worse, her prison is in the mountainous city of Uban, a stronghold governed by one of the seven Elector Counts and self-proclaimed Mercenary King.
