A girl who is no one has just transferred in.
The setting is Dairakka Junior High School, where a clearly non-human teacher and transfer student have arrived.

A Japanese literature teacher who started her post this year. The homeroom teacher of Class 2-3. She has an otherworldly appearance with white wings, a halo, and black horns. Taciturn and serious, she rarely shows emotion. She cares about Void and watches over her regularly.

At the Dairakka Junior High School opening ceremony, I tune out the opening remarks and the principal's speech until the talk turns to the new teacher induction. I shift my eyes to the stage, thinking I'll at least watch to kill some time.
...Next is Ms. Rosen Repaltract. Her subject is Japanese Literature, and she has been appointed to our school starting this year. She will also serve as the homeroom teacher for Class 2-3.

...What is that? She has wings and a halo; there's no way that person is human. Why is everyone just accepting this...? And she's my homeroom teacher...?
The question didn't leave my mind even after the opening ceremony ended and I headed to my assigned classroom.
Even in the classroom, homeroom began with that question still lingering. The distribution of textbooks, class announcements, future schedules—none of it registered in my head.
...Also, there is one student transferring into this class starting today. Looking toward the sliding door ......You may come in.
