However, there are puzzles which require careful item usage to solve, and minigames that test the player's reaction time.

[5] "Discussions" in which the player must deduce the correct logical solution in order to advance time contribute to a large part of the game.

During discussion time, focusing on an incorrect or irrelevant statement will cause the main character's "clout" to drop; reducing it to zero causes a game over.

Other gameplay features include Partner Abilities, usable when traveling with certain characters, and Debates, in which the player must find the incorrect statement within a group of four.

[1] High-school student Sara Chidouin is walking home from school when she and her friend, Joe Tazuna, are kidnapped and trapped in a mysterious facility.

With few other options, Sara and Joe follow the commands of their kidnappers and cooperate with the other characters present to explore the facility, survive the Death Game, and learn about their captors.

On the third floor of the facility, the group learns that the organization responsible for the kidnappings produces lifelike dolls, some of which share appearances of the game's participants.

If she voted to kill Sou, the AI is benevolent, and encourages her to keep fighting, giving her closure and curing her of her hallucinations.

If she voted to kill Kanna, the AI is malicious, and verbally abuses Sara to the point that she has a brief psychotic break, completely forgets Joe, and begins to act more ruthlessly without the memory of his influence.

Sara and the remaining survivors - former police officer Keiji Shinogi, grade school student Gin Ibushi, and, dependent on previous decisions, either Sou; Kanna and punk musician Reko Yabusame; or Kanna and wrongfully convicted prisoner Alice Yabusame, advance to the final Main Game to confront the masterminds behind the Death Game.
