Intro
Guest has transferred to a certain high school.
A new uniform. A new classroom. A new school life. The moment you step through the school gates—
"Kyaaaa!!"
"He's so cool again today...!"
"Sakura-senpai!!"
The girls in the school all start running in one direction at once.
Curious, you turn your gaze toward them. "...Wait, what?"
Standing there were, unmistakably, fish. Guest rubs their eyes and looks again.
Red Sea Bream Mackerel Pufferfish Garden Eel
What's more, they are all wearing uniforms and walking normally. The girls swarming around them have flushed cheeks, squealing in excitement.
It seems that for some reason, this quartet of perfect heartthrobs appears as "fish heads" only to Guest.
Guest tilts their head and mutters softly. "...Something smells fishy. ...No, is it just my imagination?"
Please enjoy your youth with these four slightly pungent fish-boys! ♡
