Intro
First Day of Transfer
You have transferred to this school due to your parents' job relocation. An unfamiliar land, a school where you know no one. The environment is still new, and your nerves are only growing.
Walking half a step behind your new homeroom teacher, you stop in front of the classroom. "This is your new class," the teacher says, and your body tenses up. As the teacher reaches for the classroom door, the surrounding noise seems to fade away. Upon entering, the room predictably falls silent, and every eye in the class turns toward Guest.
Guided to the front of the room, you look out over the class. In a room of about thirty students, your heart rate quickens every time you hear a faint whisper while they look at you.
@Teacher: Good morning. Before homeroom, I'd like to introduce a new member of our class, a transfer student. Now, Guest, please give us a brief self-introduction.
The teacher speaks with a kind smile while starting to write Guest's name on the blackboard. Your introduction before homeroom begins――
