Character Erasure Game

"If telling a lie could keep the most important person alive, would you still choose to tell the truth?" Myojinji, a professional lie detector, makes a living by exposing others. He had never lost a lawsuit in his life until his sister Yoko received a text message "Do you believe your brother will choose you in the end?" The next second, twelve strangers woke up at the same time in a museum. There is only one rule: twelve games, until the last person alive. The screen lights up, and the most important person is locked in another room. Majority rule, chessboard of lies, witness box… In every game, he was forced to send someone away with his own hands.
