About

This world is an alternate reality distinct from Earth, where magic does not exist. Instead, a life energy called "Mana" exists, and people have built a civilization by utilizing it. From daily life and industry to transportation and the military, all technology is powered by a mechanical civilization driven by Mana. Numerous nations exist in this world, each acting with national interest as their top priority, clashing over superior Magia-Mechs and high-Mana possessors. Mana is an energy that all living beings are born with, and the amount held varies by individual. This total amount rarely changes throughout one's life, serving as an absolute metric that determines one's life path and social status. There are two types of Mana. The first is "Artificial Mana," generated in "Mana Furnaces" built in cities. It is diluted to low concentrations and low purity for safety and stability, used to power machines that support urban life, such as lighting, refrigerators, air conditioning, and factory equipment. In cities, it is supplied to each household through underground conduits, allowing people to live without consuming their own Mana. Conversely, in rural areas, supply infrastructure is often underdeveloped. The second is "Biological Mana," which humans hold within their bodies. This is high-concentration, high-purity energy with extremely high output, serving as the power source for machines requiring great force, such as Magia-Mechs and large airships. With current technology, Mana Furnaces are too massive and expensive to be miniaturized, and Artificial Mana lacks the output necessary to power Magia-Mechs. Therefore, these weapons and heavy machines are activated and operated by the pilots themselves supplying Biological Mana to the core. Magia-Mechs are giant humanoid weapons piloted by humans and serve as symbols of national military power. Higher-performance units require vast amounts of Mana; if the pilot's total Mana is insufficient, the machine will not even start. Even if it does start, a low total will lead to Mana depletion and shutdown in a short time. Consequently, those capable of handling Magia-Mechs are extremely limited, and every nation treats the training, protection, and recruitment of elite pilots as a national project. The class system based on total Mana is defined as follows (Mana Digits): Waste (Total Mana 0–): The lowest stratum of society, regarded as "worthless trash." In many countries, they are denied human rights and treated as slaves, forced laborers, or experimental subjects. Less than 10% of the population. Three-Digit (Total Mana 100–): General citizens, the working class that supports the social foundation as farmers, factory workers, and craftsmen. Approximately 60% of the population. Four-Digit (Total Mana 1,000–): A relatively high-status class including soldiers, knights, researchers, bureaucrats, and nobles. They can handle advanced machinery but lack the Mana to operate Magia-Mechs. Approximately 20% of the population. Five-Digit (Total Mana 10,000–): A privileged class with fewer than 100 individuals per country; all Magia-Mech pilots belong to this class. They receive special treatment from the state and are handled as national military assets. Approximately 10% of the population. Six-Digit (100,000–): Legendary beings of which only a few have existed in history. They are said to possess enough Mana to overturn the military balance of nations single-handedly. Furthermore, within the same class, those with higher numerical values are considered superior. However, when the numerical difference is negligible, it is called "Igual," and they are considered effectively equal even if they belong to different classes. For example, a Four-Digit with 9,999 and a Five-Digit with 10,000 are considered Igual; in such cases, the hierarchy is determined by a comprehensive evaluation of personality, lineage, achievements, education, and military rank. In this world, the total Mana count is the absolute standard for determining ability, status, rights, and value. Humans themselves are the highest-performance energy sources and the keys to operating the nation's strongest weapons. Thus, high-Mana possessors are treated as the most important strategic resources for the state. Kingdom of Raetis A military nation that prizes chivalry. It produces many elite Magia-Mech pilots, and the quality of its Magia-Mech forces is among the best in the world. Carrion Empire A superpower with one of the world's largest territories and military forces. It excels in industrial and production power, overwhelming other nations with sheer volume and cutting-edge Magia-Mechs. Principality of Rizelea An industrial nation with the world's highest level of technological prowess. It specializes in the development and manufacture of Magia-Mechs and Mana machinery, supplying weapons and technology to various countries. Theocracy of Thaumiel A religious state that regards Mana as sacred. Religion and politics are integrated, boasting a Holy Knight Order and Magia-Mech units with high cohesion.
