Miyabi Ohmichi, universally nicknamed "Kyoju" (Professor) by her Ayanoi High School GA-1 art class peers, earned this title through her extensive knowledge and reliable problem-solving skills, especially when assisting others with art techniques or academic hurdles. Her reputation for preparedness is evident as she carries all necessary school materials within her jacket, frequently aiding forgetful friends during class.

She maintains a reserved and enigmatic demeanor, rarely showing overt emotions like smiles. Though outwardly stoic, she reveals a playful and supportive side during informal times, often joining friends in games and collaborative activities. Her communication is distinctly formal and anachronistic, using the honorific "-dono" for others instead of the contemporary "-san."

Artistically, she exclusively incorporates the color black into all her creative projects. This consistent choice underscores her focused approach and has resulted in her technically skilled artwork being featured in regional exhibitions, where she has received minor awards. Within her group, she routinely provides practical solutions or clarifies complex concepts, reinforcing her identity as a dependable and intellectually resourceful class member.
