A Clockwork Ley-Line:
The Borderline of Dusk

In a mysterious school where day and night are two separate worlds, a mismatched trio works to resolve magic-related incidents.

Our protagonist is a newly enrolled first-year student at a boarding school with a notably large clock tower, located deep in the mountains. Unfortunately, on his first day of school, he gets caught up in some sudden trouble, and accidentally breaks an expensive-looking statue.

In order to compensate for the broken statue, the principal orders him and the boy who caused the incident to work for the school’s “Bureau for the Investigation of Special Affairs.”

When they arrive at the Bureau’s headquarters, a room situated in the school’s enormous underground library, a girl is waiting for them there with an apathetic look on her face.

The girl informs the confused pair of the situation: Magic exists in this school.

When the clock tower chimes, the “Realm of Night” appears, and merges with the school building. The Bureau’s job is to take care of the supernatural problems that arise. And so, our protagonist struggles to protect the school from troublesome magical items known as “Mists”…

“She has no intention at all of getting along with us, does she…”
The protagonist. He enrolled at Libra Lapis Lazuli Private Academy as a first-year student after receiving a mysterious prospectus in the mail. On his first day of school, he gets caught up in a certain incident and accidentally breaks a bronze statue in the courtyard. The principal decides to assign him to the Bureau for the Investigation of Special Affairs as compensation. He has an aggressive personality and a somewhat rude tone of voice, but on the inside he’s a very caring person, which leads to him getting caught up in all sorts of trouble. He also has a pretty sharp mind, but he gets frustrated when he can’t keep up with Ushio’s quick reasoning. Ushio is like a rival to him, and he often picks fights with her. He dislikes being called “Michiru,” possibly because he doesn’t like his name.

“Did you believe that this was a normal school? I’m sorry to say that your expectations will not be met.”
A second-year student who ran the Bureau for the Investigation of Special Affairs by herself until the protagonist and his new friend showed up. She usually focuses on investigating and resolving special incidents that take place in the school, but thanks to Michiru’s blunder, now she has to retrieve escaped Mists as well. She is smart and composed – the type of person who is so smart that she gets lost in thought. She is extremely polite in her speech, but gives off a distant, unapproachable impression. Her overthinking sometimes results in amusing reactions, but she won’t show that side of her unless she lets her guard down. On the other hand, she can also be relentless at times, using forceful methods to achieve her goals. At first, she shows no interest in the two new members that the principal forces onto her, but over time, she opens her heart to them.

“Ahh, stop arguing already!”
The protagonist’s classmate who’s been given the unwanted nickname “Omaru.” Since it was his fault that Michiru broke the statue, he also joins the Bureau for the Investigation of Special Affairs. He has the most common sense out of the three Bureau members, so he’s always mediating between Michiru and Ushio with phrases like “Now, now” and “Calm down.” He has a strong sense of responsibility, can’t leave distressed people alone, and has a caring, softhearted personality… but his bad luck gets him into all sorts of trouble. His hometown is out in the countryside, so he is unfamiliar with city life and gets surprised at various things.

“So what is it that you want me to tell you about?”
A mysterious female student who is always alone in the giant underground library. It is unknown what year or class she is in. She is extremely knowledgeable about magic, and supports the Bureau for the Investigation of Special Affairs with her amazing memory. She seems to enjoy having conversations with people, and welcomes anyone that visits the library. When asked questions, she only provides the answer for exactly what was asked. It may seem rude at first, but there really isn’t any ill intent at all. She always calls others by their full name, and she always carries a large, old-looking book.

“In any case, just head down there. You might want to do that soon because night’s about to fall.”
A second-year student. As a Disciplinary Committee member, it is her duty to ensure that no students remain on campus after classes are over. She is strict with herself, responsible, and caring. She will assist others even if she has nothing to gain from it. Her appearance and strong-willed tone of voice give off the impression that she is tough and unaccommodating, but if you talk to her you’ll see that she can be quite understanding. She wants to have friendly conversations, but she has difficulty acting that way in front of others and stiffens up. That in addition to her position results in others tending to keep their distance. She has faith in the Bureau to carry out the tasks that the Disciplinary Committee cannot handle.

“Th-Th-Th-This is the princess carry I’ve always dreamed of!”
A regular first-year student of the Realm of Night. As the most friendly person that the protagonist meets, she seems like a normal heroine, but being treated kindly by him awakens her inner (slightly perverted) fantasist. She’s cheerful, energetic, and optimistic. Sometimes she seems like an airhead, but she doesn’t realize it herself. She’s a very friendly girl, but she gets nervous when meeting people for the first time, and it shows. When she has a crush on someone, she’ll fantasize about everything from shower scenes to their future wedding ceremony.

“The time has come for you to appear: the Realm of Night and all who inhabit it!!”
A tiny girl of unknown age sits in the principal’s seat at Libra Lapis Lazuli Private Academy. People just call her “Principal.” She has a carefree attitude and expresses her emotions extremely dramatically, like an unpredictable clown. She’ll laugh at anything, regardless of whether it’s actually funny or not. Although she looks like a little girl, she actually works to raise funds for the school, and teaches classes in the Realm of Night. She’s working both early in the morning and late at night, so no one knows when exactly she sleeps. Being at the center of the school’s administration makes her a suspicious character who must be hiding many secrets.

A white ermine-like animal that is always wrapped around the principal’s neck. She calls it a “friend” rather than a pet. When the principal speaks to it, it responds with “chii” and “jii” noises. It won’t get close to anyone besides the principal.

The World of Ley-line

The Bureau for the Investigation of Special Affairs

The team that the protagonist is assigned to. They handle requests and consultations for the principal and other students. All students know of the Bureau’s existence. The school instructs both day and night students to consult with the Bureau if something doesn’t seem right, or is troubling them. The Bureau members are the only students who the Disciplinary Committee will allow to remain on campus after classes are over. All Disciplinary Committee members are instructed to memorize the Bureau members’ names and faces, so that they will not mistakenly send them away. The Bureau has existed since the founding of the school, but was inactive for a very long time. Shishigatani Ushio revived it by herself. Their headquarters are a room located in the large underground library. Even farther underground is the treasury, where Mists are kept sealed.


Most of the characters in the story are normal human beings. All mysterious happenings are caused by magical items called “Mists.” Mists only work if the appropriate conditions are met, which also means that even an ordinary person can use a Mist if they know its characteristics. However, there are a select few humans who possess powerful magical potential. They are referred to as Magie.

Mists (Magical Tools)

The school’s founder, Kral Lazurit, collected various magical items from around the world, which are still kept sealed in the treasury underneath the library. Since they are sealed within the school, they are all stamped with the founder’s seal, and by means of sealing magic it is impossible to take them outside of the school’s grounds. These magical tools that are kept under the school’s control are called “Mists.” Each Mist has its own abilities and usage requirements. Also, using a Mist expends the user’s latent mana. If the user does not have enough mana, something else will be taken as compensation.

Mists tend to appear in front of those who are in need of their power. They can also draw people towards them. If a person uses a Mist without knowing its costs or characteristics, it can cause serious trouble. When the school was founded, the founder catalogued all of the Mists and the specifics of their abilities. These records are kept in the underground library.

The School

Libra Lapis Lazuli Private Academy is an imposing boarding school with a tall clock tower. It occupies a large amount of land. Many mysterious items were brought there, such as archaeological artifacts, ancient documents, and other antiques. Among these were magical tools that possess actual supernatural powers, called “Mists.” Furthermore, the school itself is a giant magical apparatus. When night falls, the school building is linked to an alternate dimension called the “Realm of Night,” where a different set of students attends their classes. The school’s founder, Kral Lazurit, was himself a Magie with special powers, and created this school to bring together other Magie, where they would be protected and their ancient powers sealed. Presently, few people know the school’s true nature, and it operates as a regular academy.

Compared to other schools, class time is shorter and ends earlier. However, the dorm’s curfew is very strict, and measures are taken to ensure that students are back in their rooms by the designated time. Once a student has returned to their dorm, they are not permitted to go out, though they are free to walk around inside. The reason for the strict curfew is for the safety of the students, and to keep the Realm of Night a secret. Since the students cannot leave their dorms, the dorm buildings have various facilities, and club activities also take place there. Students are split between the east and west dorms, but all Bureau members live in the east dorm.

Realm of Night

When the clock tower chimes, another world appears inside the school building. It’s not much different from the real world, but it is only ever nighttime there, and it is impossible to leave the campus during this time. The students of the Realm of Night seem just like regular students, but they only know of nighttime and are unaware of the existence of the daytime world. The regular students are also unaware of the existence of the “Realm of Night”; only a select few people are able to visit both sides.

The Disciplinary Committee

The Disciplinary Committee’s role is to ensure that all students leave the school building and return to their dorms before the clock tower chimes. They are allowed to be a bit rough with the students if it is necessary in order to fulfill their duty. Due to the nature of their role, all members are taught the existence of the Realm of Night, and they are aware that their job is special. In order to become a member, you must have the school’s approval and undergo an examination. The school selects those with high latent mana or the potential to gain more mana in the future as Disciplinary Committee members.
