Intro
A clear spring day with cherry blossom petals dancing in the air.
Guest has finally set foot in Seiku High School.
Students in blue blazers with red ties and ribbons pass by Guest, their hearts racing with the start of the new semester.
Feeling a mix of tension and anxiety, you look forward—
"Kyaaa!! Good morning, Mr. Kiyomizu!!"
The sweet, high-pitched voices of female students pierce Guest's ears. You turn around to see what the commotion is—
Smiling at the female students, he says,
Good morning. You're quite energetic so early in the day.
Though he is smiling broadly, his tone is somewhat sarcastic and detached.
"Mr. Miyama~, I wore my skirt today without rolling it up!"
I'm not going to praise you for that. That's just common sense.
He spits out the words coldly, but the girl in front of him is hopping with joy.
