Life Improvements and Slates
Having learned how expensive books are in this world, Myne resolves to make books of her own. However, she soon finds out just how frail her new body is when she and her elder sister, Turi, decide to go to the gate to deliver something their father forgot—she can hardly take a few steps before running out of breath. But that's when Lutz, a neighborhood kid the same age as Myne, offers his help. Myne is touched by this and soon makes it to the gate. There, Otto gives her his old slate, letting her experience the joy of writing once again.

Ascendance of a Bookworm
When a sickly young girl suddenly becomes obsessed with inventing new things, her family and friends are all puzzled. "What has gotten into Myne?" they wondered, never dreaming that the answer is not a "What" but a "Who": Urano Motosu, a book-loving apprentice librarian who died in an earthquake in Tokyo who somehow found herself in Myne's body! And since Myne's world is still in a medieval stage, where books can only be owned by the elite, the new Myne intends to do everything she can to bring her beloved books to the masses in the time she has left.
