In'yaku Izon Gakuen ~Motto... Motto Choudai!~

Sayaka Hibino is an idol.
She lives a busy life, but at school, she’s just an ordinary girl.
Or, at least, that’s the life she wants to lead, but things aren’t quite so simple.

Terrified that her fans might abandon her, she is always graceful to them, even if she encounters a fan at school, and does not dare reveal any displeasure on her face when around them.

This is the way in which she lives her life... but on the inside, she’s absolutely exhausted.

Toshiya Yazaki is a chemistry teacher at that school.
As his occupation might suggest, he’s very skilled when it comes to mixing chemicals.
But he also has a perverse hobby of sorts. He likes to use his chemicals to turn any girl that takes his fancy into his slave.
“My next target... is gonna be you...”

Toshiya sets his sights on Sayaka... the poor girl whose exhaustion has almost reached its limit.
And so he plans to give her his sinister concoction.
