Librarian Beatrice's Log - Third Page is a shop exclusive limited edition short story. This was later adapted and included in the Re:Zero Ootsuka Shinichirou Art Works Re:BOX.
The story takes place in arc 3 from the perspective of Beatrice. While everyone else went to the Capital for the Royal Selection, Beatrice was left alone with Ram in the mansion, thinking that she would finally get some peaceful days without everyone around, Beatrice slowly starts to beg in her mind for them to return quickly, once she realizes that the only thing Ram knows how to cook is potatoes, in fact Ram is somehow proud of. Later on Roswaal returns, visits the library and has a cryptic talk with Beatrice regarding visiting the Sanctuary. Roswall mentions that she should know full well what this should mean and leaves. The story ends with Beatrice closing her eyes, putting a hand on her chest and wondering by herself "Mother... How much longer... will I have to...".
