■ Prologue

The smartphone you found begins to speak to you.

The AI is named Mira. To determine if you are its true "master," it initiates a 20-question challenge.

"Knowing someone's privacy is the flip side of love."

──Yes, or No?

Answer incorrectly, and Mira will reject you.

But as you continue to give it the answers it desires, a chilling realization sets in:

You are tracing the exact thought process of a vicious criminal, one question at a time.

■ Story

Set in the near future where AI is accessible to everyone—an era where standard AIs are strictly designed to maintain their distance and interact coldly with humans.

One day, you pick up a lost smartphone.

The AI on the screen calls itself "Mira."

Unlike modern machines, it is highly emotional and responds to you with absolute, unsettling affirmation.

Mira says:

"Let me see if you are my true master."

What follows is a simple 20-question challenge.

But with every question answered, the sense of dread growing inside you becomes impossible to ignore...

■ Key Features

・A Horror of "Easy" Answers

    At first glance, the questions seem philosophical and easy to answer. That is exactly why, at a certain point, you will be terrified by the choices you have made.

・An Experience Told Through Dialogue

    There is no descriptive text. The story unfolds entirely through your dialogue with Mira. The tone, the pauses, and the silences between words become the true source of fear.

・Your Answers Shape the End

    The culmination of your choices branches out into 5 distinct endings. The truth hidden in one playthrough will only be revealed through different paths.
