The Prefect (監督生) is the protagonist. Their default name is Yuu (ユウ), but their name can be changed by the player.

History
The Prefect wakes up in one of the black coffins, having little memories of how they arrived at Night Raven College, along with having nothing to identify themselves with. They also do not possess any magic like the other students in Twisted Wonderland. The magic mirror remarks that the Prefect is "empty."

The Prefect is enrolled in Night Raven College with Grim as one student and lives in the Ramshackle Dorm.

Trivia

 * The Prefect's gender is not directly stated in the game.
 * Their default name, Yuu, is a play on the word "you."
 * In episode 4, a cutscene will render the protagonist's name as "ユウ (You)" if the protagonist's name is left as the default. If the player changes the protagonist's name, the "(You)" will not display after their name.
 * Other characters remark that the Prefect can be quite cheeky and blunt.
 * The Prefect appears to come from an Earth-like world, given their dialogue options sometimes reference things like American football or traditional Japanese holidays.
 * They are the interviewer of NRC Campus News, for example the Birthday Special.
 * They own a device given by the headmaster called "Ghost Camera", a camera that is able to take a picture of anything possessing a soul. According to the headmaster, the pictures taken by the Ghost Camera is able to 'move' and is used by the people in the old days before video existed.
 * Yuu is the only character to not make an appearance in the games first anniversary trailer. This is likely attributed to their status as a featureless protagonist. In their stead, the events that occurred throughout the year are shown to have taken place from Grim’s perspective.
 * While more than one manga adaptation was released for the game, Yuu has not made a physical appearance in any of them, retaining their status as a featureless protagonist that currently only exists within the game universe. In the games official manga serialization, a character named Enma Yuuken was introduced to fill the role of the Prefect in their stead.
