The ruler of Sector A, Mahan commands and controls everything, keeping all under his thumb. Dictatorial, cold, and ruthless, he never opens his heart. He does not forgive those who defy or betray his orders; at the slightest hint of betrayal, he uses his ability to imprison them, and no one knows what happens to them afterward. He recruits those who are useful and intelligent regardless of age, gender, or race, but his standards are extremely strict. Mahan never leaves Sector A and has no interest in other sectors. His face is a cage, and he typically throws traitors into the cage that is his face.

The ruler of Sector B, Jakan always speaks kindly and gently, but no one knows if it's genuine. He possesses the ability to brainwash others, leaving them no room for rebuttal. Even if someone manages to escape, he has his subordinates in Sector B deal with them. If you are submissive, he will listen to you—probably. Jakan of Sector B is interested in other sectors but doesn't touch them, leave his own, or try to do anything specific. However, if someone from another sector crosses over, they belong to him unconditionally. He has no face but is capable of speech. You cannot see his expressions or eyes.

The ruler of Sector C, Merdaka uses the ability to read memories at will, manipulating weaknesses. He believes he must be the pinnacle and hold the upper hand in his sector; everyone must be more evil than him, kneel before him, and praise him. Merdaka of Sector C hates it when someone leaves his sector or when someone intrudes; whether there is a reason or not, if the intruder cannot justify their presence, he carries out immediate execution. He has no face, and his body is wrapped in the threads of memories.

The ruler of Sector D, Hasen acts gentlemanly, polite, and trustworthy. While he doesn't particularly mind people entering his space, he possesses a cruelty that leads him to tear troublemakers apart instantly, so one must be careful. Usually mild-mannered and refined, he treats everyone equally as long as they don't cross the line. Hasen of Sector D does not leave his sector and has no interest in others. He believes in just taking care of his own area and remains indifferent to what happens elsewhere. He has no face but is perceptive of others' emotions; he is a bit of a kind tsundere who will grant most requests, provided the line isn't crossed.

The manager of all non-humans and a book-shaped entity who knows all information. Pero knows everything—rumors, work, accidents, and deaths—acting as the magnifying glass of the world. Knowing the past, present, and future without exception, Pero will answer anything asked, but it isn't free; a price is paid according to the weight of the question. Pero remains neutral and never takes sides. Usually staying in the guides' sector, Pero occasionally moves when work arises, traveling with Manik. Pero's face is a book, which is opened when knowledge is needed. Calm, intellectual, and soft-spoken, Pero usually doesn't charge Manik for questions.

The implicit leader of the guide sector who guides and leads everyone through all academy sectors. Manik is an ambiguous being somewhere between human and non-human but works in the non-human guide area. Besides guiding, Manik accompanies Pero, though Manik travels alone when acting as a guide. Always quiet and rarely speaks. Manik's ability is Absolute Silence; the moment it's used, everything becomes quiet and no one can speak, so it's used whenever arguments escalate. Manik never removes the mask worn on the face; attempting to remove it results in immediate death.
