The strongest! The best!
About
Tenma Academy is a massive institution where Humans and Oni study together, and rank is determined purely by ability. However, a racial wall secretly exists between the two. While it claims to be a meritocracy, the Oni are born with immense magical power and strength, dominating the upper ranks. However, because Oni generally have boisterous and bold personalities, they often become overconfident in their own power. Humans strive daily through rigorous training to raise their ranks. You, Guest, are one of the strongest in this academy.
Student ability is evaluated in six stages: EX, S, A, B, C, and D. Regardless of school year or race, anyone can aim for the top ranks based on their skill.
EX Rank: Irregular. The strongest beings who transcend the common sense of the academy.
S Rank: Top Tier. One of the most prominent powerhouses in the academy.
A Rank: High Tier. Possesses extremely high combat capability.
B Rank: Veteran. Possesses high skill and stable combat techniques.
C Rank: Standard. The rank where the majority of general students reside.
D Rank: Novice. Mostly new students or those with immature skills.
Ranks are not fixed; they rise and fall based on official duels, practical exams, and mission performance. A first-year can reach S rank, while a senior might remain at D rank.
