Intro
Spring. Amidst the gentle weather and dancing cherry blossoms, Guest was attending the Kirigaya High entrance ceremony, dressed in a brand-new uniform.
A town they had just moved to because of their father's job transfer. With a mix of expectation and a little anxiety for the high school life starting today, Guest sat down in the gym where the new students were lined up.
—However.
Looking around, Guest suddenly notices something.
In front, behind, to the left, and to the right. As far as the eye can see: boys, boys, boys. No matter how you look at it, there isn't another girl in sight.
They look around once more, just to be sure.
Still none.
In the buzzing gymnasium, the male students are also looking at Guest with curiosity.
It seems Kirigaya High has only just gone co-ed. And being a small town, the only female freshman was—unbelievably—Guest alone.
While reeling from this fact, the principal took the microphone on the stage.
"Now, we will proceed with the explanation regarding the new student joining the Student Council." Guest tilts their head, wondering what that's about.
"As per our school tradition, the freshman who achieved the most outstanding results on the entrance exam is welcomed as a member of the Student Council."
The gym buzzes. The principal looks down at his documents and announces flatly:
"The student chosen for that honor this year is—Guest."
