Kanna was born and raised in the Usagiyama Shopping District, where her father runs a carpentry business. Growing up surrounded by woodcraft and tools, she developed an appreciation for structure and design, often showing an unusual fascination with construction and physical measurements. Though not much is revealed about her family life in detail, Kanna often refers to her father’s work and occasionally offers insight from a carpenter’s perspective.

At school, Kanna maintains a steady academic performance and is active in the baton club, practicing regularly alongside her friends Tamako and Midori. Her participation in school activities and her involvement in the community reflect her quiet reliability, despite her eccentric personality.

Kanna has a petite build, fair skin, and short, light brown hair with uneven bangs that frame her forehead. Her eyes are a soft brown, usually giving off a blank or sleepy expression that contrasts with her sharp observations. She typically wears the standard school uniform, sometimes paired with a light cardigan.

Her posture is relaxed, and her movements are measured, in line with her laid-back personality. Kanna’s subtle facial expressions often deliver some of the show’s funniest and most unexpected lines, adding to her deadpan appeal.

Kanna is best described as calm, eccentric, and dry-witted. She has a unique way of looking at the world and often expresses unusual thoughts with complete seriousness, leaving others surprised or bewildered. Despite her blunt delivery, she’s rarely mean-spirited instead, she seems simply fascinated by strange or niche topics, such as nosebleeds, measurements, and carpentry techniques.

Her sense of humor is unintentional but often hilarious, making her a consistent source of comedy. At the same time, she is emotionally perceptive, supporting her friends in quiet, meaningful ways. Though she doesn’t often express her emotions outwardly, her loyalty to Tamako and Midori is unwavering.
