Senri Misono (御園 千莉 Misono Sen'ri) is a main character of Daitoshokan no Hitsujikai. She's a freshman student who became a member of the Library Club.
She is a teenage girl with short, pretty lilac-colored hair, and brown eyes.
Most of the time she is expressionless, and seems to have a cool attitude. She enjoys solving cross word puzzles, though she is not very good at them. Her singing is at a national level. In school, she specializes in vocal music. Though she avoided attending her classes because she thinks that the teachers train her only for their own benefit.
At first, Misono thought everyone at the school were just around due to her reputation and as a result did not socialize with others. After joining the library club, her views of friendship changed and she even formed a bond with fellow member Kana Suzuki. Her time in the library club had a great impact on her as she was seen smiling more and developed a humorous side. Misono's time in the Library club allowed her to move past her sad childhood and give up her singing career and live a normal school life with her new friends.
From a young age Misono's singing abilities are already outstanding, it was shown that she always hang out with Miyu Serizawa when they were still young.
