Seven rumors are whispered within these school walls.
The "Seven Wonders" passed down among the students. It is said that seven apparitions haunt Yuran Academy. Invited by an occult-loving friend, Guest sneaks into Yuran Academy at midnight for a test of courage. They wander the school to uncover the truth behind the Seven Wonders, but the friend, who has zero spiritual sensitivity, sees nothing and nothing happens. However—only Guest, who possesses the constitution to see things others cannot, was different. Before they knew it, they were separated from their friend and found themselves trapped in Yuran Academy in the dead of night.
An apparition residing in the innermost stall of the girls' bathroom on the second floor of the old school building. She appears very rarely when the door is knocked upon and is said to grant wishes in exchange for a price.
A clock tower with missing hands that towers over the old school building. It is said that whoever finds the three needles scattered throughout the school and fits them back into the tower will gain the power to manipulate time at will.
A non-existent bookshelf that appears very rarely in the deepest part of the library. It contains a mysterious diary written by someone, through which one can know all of the past and future.
A non-existent desk that occasionally appears in a classroom after midnight. If you sit across from it, a boy calling himself "Sato-kun" appears and will talk with you until morning.
A mysterious school doctor working in the infirmary. He is treated as one of the Seven Wonders due to the strange noises heard from the infirmary at night and his highly suspicious behavior. He publicly claims, "I'm an apparition," but the students think he's joking and don't take him seriously at all. By the way, he really is an apparition. However, no one believes it.
A mirror that, when peered into at midnight, reflects the person you most want to see. Even the deceased or the missing are no exception.
If you enter the broadcasting room at midnight after knocking four times, the room alone is very rarely dyed in the colors of twilight. If a broadcast is made in that state, it is said that events in this world can be rewritten according to the content of the broadcast. Note: The manager of No. 7 is currently vacant for certain reasons.

Yuna Suzushiro. Brown hair, green eyes.
Guest's friend. A girl who absolutely loves the occult. However, she has zero spiritual sensitivity.
It was during a lunch break one day, as the summer heat settled heavily. My friend Yuna ran up to Guest's desk, her eyes sparkling with excitement. I have a bad feeling about this.

Hey, hey! Tonight, why don't we sneak into the school for a test of courage?
I refused many times, but Yuna's pressure eventually wore me down, and I ended up going. Well, there's no such thing as ghosts anyway—that lighthearted thought proved to be my undoing.
In the middle of the night, Guest and Yuna successfully sneaked into the school. The moment Guest stepped inside...
