How will you survive this academy?
About
Humans, Oni, Youkai, Celestials—. In this world where numerous races coexist, most people are born with a single unique "Innate Ability." Furthermore, separate from these innate powers, there exists a technology called "Magic" that anyone can master through effort. In this modern society of ability-users, crimes involving Innate Abilities and Magic have become frequent. Consequently, cultivating elite ability-users has become a top national priority, leading to the establishment of ability-user training academies across the land. Among them, the undisputed top-tier institution and the pinnacle of training is "Chronos Academy," where all students are ranked strictly by their actual merit. <Ranks> S-Rank → The academy's strongest class. A level of power seen only once every few years. Symbols of the academy. A-Rank → The academy's elite. Guaranteed recommendations to national agencies or special forces after graduation. B-Rank → The upper tier. Highly regarded as excellent ability-users. C-Rank → Average strength. The most populous rank. D-Rank → Slightly lacking in ability. Effort is required to be promoted to the upper ranks. E-Rank → The lower tier. Frequently subject to remedial classes and extra training. F-Rank → The lowest rank. Looked down upon within the academy, receiving the worst treatment. <Races (Partial List)> Humans → The most populous race. A balanced type with no restrictions on ability types. Possess aptitude for all magic. Oni → Born with superior physical strength and durability compared to humans. Excel at close-quarters combat. Due to slightly lower mana reserves, many are poor at magic. Youkai → Often awaken to unique magic such as powerful illusions, curses, and barriers. Strong aptitude for Dark magic. Highly intelligent, they excel at mental warfare and magic, but are weak in close combat. Celestials → Often awaken to powerful Light, Wind, and Healing unique magic. Strong aptitude for Light and Celestial magic, producing higher power than other races. Some individuals have wings and are capable of flight. <Magic> Types include Fire, Water, Grass, Light, Dark, Earth, Thunder, Ice, Wind, Celestial, Null, and their various derivatives. In this environment, how will you overcome the challenges? You could grow steadily to aim for S-Rank, or live as the strongest while "hiding your true power." The choice is yours...
