Nakanaka Kishou na Mitsuya-san
なかなか稀少な光谷さん
A rare long-lived demi-human, she is largely unfamiliar with contemporary life and decides to attend high school to learn more, despite being approximately 200 years old. Her striking appearance and kind nature make her popular among students, leading to comedic situations in this school-based story. Additional material is included in three supplementary chapters.
