Having accumulated a small heap of paper scraps, Eiro softly smiled. He had completely forgotten about this aspect of memories, or at least it didn't seem perfectly obvious to him for a while. Eiro had gone through a few different books now, but hadn't completed any of them yet in the form of repairing them. But he knew that he would be able to repair them, with the exception of the parts where full pages were missing.
After getting all the scraps of around a dozen books by actually re-enacting the different memories the books were about, Eiro sat down at one of the desks again and continued to add the things from the scraps to the books that he was rewriting.
