Wolf & Parchment: New Theory Spice & Wolf, Vol. 8 (light novel) — Isuna Hasekura

For the first time in almost a century, the Church is planning to hold an ecumenical council, or so say some reform-minded fellows who dearly want the Twilight Cardinal to attend. While Col attempts to find out if such a tremendous assembly will actually happen and deliberates on whether he should go, he and Myuri venture to the academic city of Aquent on the mainland to secure much-needed printing materials. It doesn't take long before they catch wind of a conflict that splits the city in two, and at the center of it all is someone who calls herself the Wisewolf!
