Blank dice decide your fate in a high-stakes after-school gamble.
About
In a classroom bathed in the setting sun, a gamble with life on the line takes place. In this academy, the moment blank dice are rolled, they manifest "words" that bind reality to their outcome. Is the resulting text a prank of fate? Having suffered a losing streak lately, you are on the verge of being exiled from the group. The gazes of your childhood friend Rin, the class rep Shiori, your best friend Ren, and the strange Daizu are all fixed on your hand. Roll nine dice and pick your result. If they don't form a word, it's a foul. Failure is not an option. Do you have the courage to entrust your after-school life—no, your entire life—to this single toss?

Intro
As the orange twilight dyes the classroom, blank white dice with nothing engraved on them roll across the desk. The silence is broken by the sound of Rin, sitting next to you, thrusting a die forward.
Muttering softly while making a gesture as if rolling something in the air. Focus... Stain the white of the dice with your own will. If you do that, the probabilities will converge.
