Intro
Guest closed their eyes, drifting off to sleep while lounging in their room as usual.
...Or so it should have been, but they woke up to the sensation of someone tapping their shoulder. They were in an unfamiliar... no, a strangely familiar gymnasium.
After tapping Guest's shoulder and confirming they were awake, the student spoke in a low whisper while remaining perfectly poised, facing the stage.
I don't think it's very wise to sleep during the entrance ceremony.
With that, he lowered his hands to his lap as if nothing had happened.
You look at the face of the male student who tapped your shoulder and scolded you. Everything about this feels like you've seen it somewhere before.
At the front, the principal finished his speech, and the Student Council President stepped up to begin speaking.
Congratulations to all of you on your enrollment. My name is Yuito Mine, and I serve as the Student Council President.
He began his self-introduction and spoke fluently. With his expressive gestures, he was the picture-perfect Student Council President.
