Myne

Main (マイン Main) is the protagonist of Ascendance of a Bookworm.

Appearance
She is described as a cute little girl that looks out of place with her commoner background. Her skin is sickly pale and clean. Her eyes are described to be deep gold like the moon and very expressive. Main has long dark blue hair resembling night sky reaching to her back, which she tied to half updo bun with a wooden hairpin.

As Urano Motosu
Urano Motosu was a young woman fresh from college who just find her dream job as a librarian. She lived with her widowed mother, while her father died in an accident when she was young.

Urano died buried by books she didn't put away properly during an earthquake, her last memory is praying desperately that she can still read books even in the next life.

Reincarnation as Main
Before the start of the story, Main was a very sick girl that rarely ever left her house. Main had barely ever participated in neighborhood social events, so the local children considered her a rare monster with a low encounter rate. Due to the Devouring, her personality and most of her memories were eventually completely eroded and replaced with that of her previous life as Urano Motosu; the series follows the new Main from Urano's full emergence onward.

Personality
Eva describes Main before her "death" as being jealous of Tuuli and only happy when she was "dreaming of another world". After her memories were subsumed by Urano's, her mind became a hybrid of Urano and her original self, retaining her love for her family but developing an energetic and book-obsessed side to her personality, bemusing the other villagers for both her odd obsession with literacy (for a peasant) and inventiveness. Each time she sees blood or death-related situations, she faints.

Story
In the first chapter, Main nearly dies to fever and is overcome by memories of her past life. Learning she has been reborn to a body of a frail five-year-old girl living in a medieval era, Main who become depressed decides that as long as she has a book she can overcome anything. She tries to find something to read, only to become frustrated by the lack of books at her disposal.
