本好きの下剋上 フェルディナンドの館にて
- Thread starter MangaDex
- Start date
there are a lot off little stories at the end of each of the LNs that show the perspectives of side characters. These two are the only ones so far that have also made it into the anime. So yes, there is plenty material. As for standalone books, that would be the Hannelore spinoff that is currently being written/translated.
