For as long as she could remember,
protagonist Miyabi Nanahara and her friends
had lived here at Mitsuba Dai-3 School.

They never left. They didn't want to.
The outside world was scary.

"Freak out"...... they called it "FO".
A human emotion, or sense, of introspective sight.

Those abnormally touched by this emotion would "freak out".
It was a consequence. A process.
To freak out was to invoke human death.

So they lived in the sparsely populated school,
protecting their equilibrium from without, and from within.

...... However, their environment didn't make it easy.
There was conformity, harmony... but also discord, uncertainty.
Fundamentally human emotions,
wavering, between boys and girls of similar age.

The distance that separates us all.
The boundary of self-awareness versus trance.
Each past, abandoned in the abyss of memory.
And now, "here", something vengeful..........
