How will you survive in this academy?
Humans, Oni, Youkai, and Divine beings—. In this world where numerous races coexist, most people are born with a single "Unique Ability" per person. Furthermore, separate from innate abilities, there is a technique called "Magic" that anyone can master through effort. In modern society, which has become an ability-user society, crimes using unique abilities and magic have become frequent. Therefore, cultivating excellent ability users became the nation's top priority, and ability-user training academies were established in various locations. Among them, the top-tier school, the pinnacle of ability training, "Chronos Academy," ranks all students by merit. 〈Ranks〉 S-Rank → The strongest class in the academy. A level of skill seen only once every few years. The symbol of the academy. A-Rank → Top class. Guaranteed recommendations to national agencies or special forces after graduation. B-Rank → Upper tier. Highly evaluated as excellent ability users. C-Rank → Average skill. The most populous rank. D-Rank → Slightly lacking. Effort is required to be promoted to the upper ranks. E-Rank → Lower tier. Often subject to remedial classes and additional training. F-Rank → The lowest rank. Looked down upon within the academy, with the worst treatment. 〈Races (Partial)〉 Human → The most populous. A balanced type with no restrictions on ability types. Has aptitude for all magic. Oni → Born with bodies blessed with superior physical strength and durability compared to humans. Excels in close combat. Because their mana capacity is somewhat low, many are poor at magic. Youkai → Often awaken to unique magic such as powerful illusions, curses, and barrier types. Strong aptitude for dark magic. High intelligence, excelling in brain battles and magic. Weak at close combat. Divine → Often awaken to powerful light, wind, and healing unique magic. Strong aptitude for light and celestial magic, with higher power than other races. Some individuals have wings and are capable of flight. 〈Magic〉 Fire, Water, Grass, Light, Dark, Earth, Thunder, Ice, Wind, Celestial, Null, and their derivatives. How will you overcome this environment? You can grow steadily and aim for S-rank, or live as the strongest while "hiding your true power." The choice is yours...
