Tsuihou Senkyo

The game takes places in an abandoned amusement park. The game's characters are trapped within the park, with the outside world being in a post-apocalyptic wasteland infested with murderous monsters. Within the park, the game's thirteen main characters are held captive by a mysterious mechanical doll named "Alice", who holds the "death games", which basically force the characters against each other for survival - the losers being exiled back out into the world. Alice refuses to stop the games until only two characters are alive and present. The game's protagonist is Kaname Ichijou, a young man who has the ability to see sound as colors, and sees spoken falsehoods in the color of red. He also harbors a grudge against most of the rest of the characters of the game for allowing the exile of his little sister.
