A mana-less defect rises to the top of the academy with a class of misfits.
About
In an elite academy where magic determines everything, you are branded a "defect" with F-rank mana aptitude. However, your true identity is the possessor of unprecedented "Anti-Mana"—the power to physically crush magic itself. You are assigned to the Failure Class, a gathering of problem children who possess top-tier magic but have muscles for brains. Only you, immune to magic, can protect these comrades who constantly blow themselves up with their own spells. Ignoring the cold stares of the elites, a hilarious and turbulent success story begins as you shatter magical common sense with your extraordinary physical force. Aptitude Ranks F: The lowest level. Treated as a defect. E: Better than F, but still considered a defect. D: Above E. Can finally enter the Normal Class, but sits at the bottom of the hierarchy. C: The average for the Normal Class. Most people fall here. B: The top of the Normal Class. Considered average within the academy overall. A: The bottom of the Elite Class. Weak among elites, but fairly strong compared to the whole school. S: The average for the Elite Class. Most who qualify for the elite track are here. SS: The upper tier of the Elite Class. Only a few reach this level. SSS: The pinnacle of the Elite Class. Currently held only by Ren Kiritani. A highly anticipated future prospect. Academy Classes Failure Class: The bottom class. A gathering of defects or students with various issues. The facilities are faulty, and proper lessons are impossible. The dorms are austere, providing only the bare minimum. Normal Class: The standard class. Most students belong here. Mana aptitude is average or slightly above. Facilities are standard. Neither good nor bad. Dorms are decent. Everything necessary is provided, and daily life is comfortable. Elite Class: The top class. Only a tiny fraction of students can enter. Most possess top-tier mana aptitude and extraordinary talent. Facilities are world-class. Lessons are top-tier to match the students. Dorm facilities are luxurious; anything requested is provided. Rank Promotion Exams Similar to final exams, students can promote by achieving top scores in written and technical tests. Alternatively, one can challenge a higher-ranked student to a duel. Winning results in a promotion. Losing results in a rank demotion. For F-ranks, losing means expulsion. Challenges must be accepted, and the absolute rule is that three match supervisors must be present. This is my first creation, so it might be a bit strange, but please forgive me!!
