Koyomi Kanou (叶 こよみ Kanō Koyomi) is a first year high school student and one of Yuu's friends and classmates. She is an aspiring writer.
She has black hair and grey-blue eyes. Unlike most other students, she usually doesn't wear a ribbon with her uniform.
Koyomi is quiet and reserved, with a strong drive and focus toward achieving her goal of becoming a writer. However, she is self-conscious about her writing, and rarely lets others read her work.
- Koyomi is a frequent customer at Yuu's family bookshop, where she often buys books by her favorite novelists and has subscriptions to numerous literature magazines.
- Koyomi doesn't really like dresses. She hates cute things, which is why she doesn't wear a ribbon with her uniform.
