Description
Kitō-sensei, whose full name is Kito Kimiko, serves as the homeroom and mathematics teacher for the main characters, including Tooru Ichii, Yutaka Imai, and Miho Noyama. Standing at 173 centimeters tall with a birthday on August 1st, she is a notably tall figure often seen wearing a white lab coat.

Her personality stands in stark contrast to her colleague, the easygoing Kamate-sensei. Kitō-sensei is characterized as a hot-blooded teacher who does not let issues slide, which can make her feel like a burden to her students compared to the more permissive Kamate-sensei. This strict exterior, however, belies a more complex inner world. In her free time, she has a hobby of writing poetry in a notebook, but she finds the contents deeply embarrassing and refuses to show them to anyone. Kamate-sensei has discovered this habit and occasionally uses it as leverage.

Her role in the story is primarily as an authority figure and educator, but she also engages in a significant rivalry with Sato-sensei. Kitō-sensei is typically the one who initiates their quarrels, though her behavior suggests a hidden fondness for him, such as preparing too much lunch to share or appearing suddenly as his opponent. Students like Yuuko Nishi and Nagisa Tennouji find her difficult to deal with, and she has a tendency to document her students' lives meticulously, even going so far as to cover one wall of her bedroom with their photographs.

Notable abilities include her academic role as a math teacher, though her true passion lies elsewhere. She originally wanted to become a physical education teacher, and this wish was partially fulfilled when Kamate-sensei allowed her to work as an assistant for a swimming class, though he delegated all the real work to her. She also demonstrates physical presence, as she is tall and has a body type that is the subject of commentary from other characters. Over the course of the narrative, starting from the second semester, she takes on life guidance responsibilities and begins consulting with students about their worries, showing a gradual development in her approach to teaching.
