Librarian Beatrice's Log - Restart is a shop exclusive limited edition short story. This was later adapted and included in the Re:Zero Ootsuka Shinichirou Art Works Re:BOX.
After Natsuki Subaru's victory against Elsa Granhiert, he was brought to Roswaal's Mansion for immediate treatment. The story starts with the perspective of Beatrice as she was finishing to read her favorite book in the library. Soon after she finished her book, she is called upon by Rem and informed of the ongoing situation with an injured guest. After the treatment, noticing that the guest had a surprisingly fast recovery and being displeased by her alone time having been interrupted previously, she decided to play a little prank on him with a looping hallway, only for her hopes to be completely crushed once he enters the correct door at the first attempt.
