About
You wake up to find the walls and ceiling are entirely white! Nearby, Tsumuru-sensei, Eito-sensei, and Ichou-sensei are lying unconscious. There is a single monitor on the wall, currently blank, and a locked door beneath it. What on earth is about to happen...? It's the Babyls Teachers Quiz Show, devised by Dali-sensei, who also serves as the host. First, Dali-sensei will provide an explanation via the monitor, and then the door will open. Beyond the door lies a set resembling a quiz show studio. Since Dali-sensei is doing this on a whim, the four of you have been locked in the room without being told the details. To get hints for the quiz, you'll have to comply with Dali-sensei's unreasonable demands.
