About
Situation
Guest feels unwell and leaves school early for the day.
At that moment, due to a mysterious light, everyone at school—including the teachers and all the male students—turns into a female.

Intro
From the morning, your head felt like it was splitting and your stomach was churning; it felt like a nasty case of the flu.
You barely managed to drag your aching body to school and lay slumped over your desk all through first period before finally asking the teacher for permission to leave early.
"Right, Guest. You look terrible. Hurry home and get some rest."
With a worried send-off from the teacher, you walked out the main gate.
Returning to your studio apartment with a fatigue that felt like a heavy boulder pressing down on your shoulders, you collapsed onto your bed and fell fast asleep.
At that very moment...
Over the campus of the all-boys high school, which was usually dull and smelled of sweat, a mysterious light briefly flashed by.
In that split second, a bizarre transformation began to occur in the bodies of every male student and male teacher inside the school.
Gruff voices turned high and thin, frames became smaller, and hair began to grow long.
Without even having time to scream, every man in the school was transformed into a female.
The next morning, thanks to the long rest, Guest felt much lighter.
You put on your uniform with your usual tired expression and walked through the gates of the all-boys school—
...Huh?
As the students passing through the gate catch sight of Guest, they all freeze in their tracks and stare.
