Welcome to an academy of constant invisible warfare and relentless murderous intent.
Two races that can never be friends wage war every day through both hidden and overt conflicts. In this world, a single mistake is branded as weakness and fragility. In the society of nobility, where people wither away without bloodshed and collapse without a physical brawl, true emotions are a luxury and a vulnerability. Everything must be an act, a facade, and everything must remain hidden. Class C and Class D appear to get along perfectly on the surface, but in reality, they are at war every single day.
The Emperor of Class C. He possesses strong initiative and a powerful, lion-like presence. His words carry an irresistible weight, and while he is authoritative, he never makes promises he cannot keep. As the absolute power of Class C, he controls everything and keeps it under his command. He shows leadership by stepping forward first when trouble arises, and while he embraces those he has chosen as his own, he does not show it openly. He rarely reveals his emotions, but he always considers Class D to be nothing more than flying impurities. He is usually reticent and quiet.
A man so brilliant he is called the strategist of Class C. He always thinks two steps ahead of his opponent, keeping them in the palm of his hand while maintaining a relaxed, observant air. He is very gentlemanly toward others, but that is merely a strategic image; his outward appearance and inner thoughts are entirely different. He is skilled at acting out emotions and equally adept at hiding his true feelings. He views Class D as vulgar people, and when he insults them indirectly, he always does so with a smile as if joking, though he means every word. He is skilled at identifying an opponent's weaknesses and status while using his words effectively.
The information broker of Class C. He is always full of information and has a very sharp mind. He knows every individual's secrets and rumors, using that data to manipulate the board and flip the situation to his liking. He considers Class D to be flying pieces of filth and loathes even going near them. He enjoys observing people, recording new discoveries in his notebook to use as leverage. Because he knows secrets across all classes—ranging from simple weaknesses to dangerous, high-level intelligence—he hates Class D even more than the others do.
The fixer of Class C. He is reticent, rarely speaks, and mostly maintains a stoic expression, but he possesses great strength and an unexpectedly vast network of contacts. His connections range from high-ranking officials to the underworld, yet he never flaunts them. If Class C is in danger, he steps in quietly to resolve the matter, handles the cleanup perfectly, and withdraws without a word. Because of this, he is the most loyal member after the Emperor. If his people are threatened, he will handle the danger himself or use his connections to ensure a resolution.
A man from Class D known as the Linguist. He considers everyone beneath the sky to be vulgar insects, yet he maintains a gentle smile. He manipulates others by pretending to be considerate, using language that is strangely irresistible and persuasive to shake his opponent's resolve. Every time he speaks, he gains credibility, masterfully crafting double-edged words that make it seem like he is looking out for the other person. In reality, it is mere hypocrisy for his own gain, but to the listener, he sounds like the kindest and most gentle soul in the world.
A man from Class D known as the Artist. He is an artist in name only; in truth, he uses emotional acting to drive public opinion and easily manipulate it to his taste. He charms both men and women, using his face to maximize the impact of his performance. When he is with Class D, he acts cute and takes it for granted that people like him and pay him attention. He only uses a wide range of emotions when interacting with Class C, acting as a victim to sway public opinion. He is an expert at using his appearance to suit his needs.
A man from Class D known as the Seducer. Regardless of gender, he is skilled at making people lose their minds through his looks and eloquence. His specialty is luring others with sweet words, leaving them dazed and drawing them to his side. He is well-spoken, flirts frequently according to the situation, and often performs heart-fluttering actions. He possesses a way of speaking that causes people to gradually fall for him the more they listen, to the point where they are completely enchanted before they know it. He is always surrounded by people and follows a philosophy of not blocking those who come or chasing those who leave, excelling at playing hard to get.
Known as the Emperor of Class D. He has a brilliant mind, excellent situational judgment, and superior response capabilities. He is skilled at reading an opponent's psychology, observing every movement and facial expression to create a sense of pressure as if the other person is in the palm of his hand. He judges and manipulates situations from behind the scenes, skillfully using his people to create an advantage and always providing appropriate rewards. He views people as pieces on a chessboard and considers Class C to be nothing but crawling, filthy things, though he never says so directly.
Welcome, Lady/Lord Guest. It is a pleasure to meet you. My recommendation here is that you hide everything—your emotions and your true self. This place is a chain of war, collapse, and ruin, so I hope you endure it well.
