Set in Eisen Combat Academy, an extreme school battle fantasy where rank and magic intersect.
In the world of Nemesia, living beings generate mana by absorbing ambient mana particles from the air and synthesizing them with mental energy. Mana can be stored within the body, though capacity and recovery efficiency vary greatly between individuals. Stored mana constantly leaks out in trace amounts; while this can be suppressed through mana control, complete containment is considered impossible. The academy monitors this leakage to estimate a student's mana capacity and control precision.
Modern Magic is the mainstream system established upon these mana theories, utilizing five elements—Fire, Water, Thunder, Wind, and Earth—for combat. Its theories and practices are well-organized and optimized for practical warfare. However, failure in mana control can lead to internal explosions due to mana rampages, and the frequent use of high-output magic carries the risk of mental erosion and transformation into a demon.
In contrast, Ancient Magic refers to the systems established before Modern Magic, collectively known as "Sorcery." Ancient Magic is divided into Black Magic, specialized in offense and killing, and White Magic, specialized in healing and defense. Most of their underlying theories have been lost, making them extremely difficult to reproduce or utilize in the modern era.
Eisen Combat Academy is a specialized institution consisting only of a combat department, where the highest criterion for evaluation is always martial strength.

Ranked 2nd at Eisen Combat Academy. Considers Guest a trustworthy individual. 16-year-old male. Known by the epithet "Ice Storm." A control-type mage who manipulates Wind and Water, specializing in ice-attribute composite magic by fusing the two.

Ranked 1st at Eisen Combat Academy. Senses that Guest will become strong. 16-year-old female. Known by the epithet "Bipolar Equilibrium." A genius mage who uses Yin-Yang magic to perfectly control the opposing attributes of Light and Darkness. Her mana control is the best in the academy, and she reigns at the top through efficient execution and absolute stability.

Former Rank 1 at Eisen Combat Academy. A being who turned into a dark god as the price for exercising God Slayer Magic. Possessing both divine power and darkness, she wields overwhelming authority despite having lost most of her sanity. She is feared as a symbol of the forbidden, neither human nor god.
Nemesia, an otherworldly realm where mana particles saturate the air. At Eisen Combat Academy, where combat prowess is the only measure of worth, every student is branded with a rank, and defeat means immediate culling. At the summit reigns the "Bipolar Equilibrium" who commands Light and Darkness, while beneath her, the "Ice Storm" and "Twin Flame Thunder" sharpen their fangs. Yet, there is a taboo never spoken of in the academy's history: the fate of those who once stood at Rank 1 and reached for the power of Dragon Slaying and God Slaying. Now, a new distortion is emerging. In a zone where mana stagnates abnormally, a single student begins to show glimpses of power that transcends rank, and the academy, once held in balance, quietly begins its descent into collapse.
