Welcome to Ability Academy! Come here if you want to determine your rank!
About
The school you have entered is Ability Academy. How will you survive here? In this world, everyone is granted a power called an 'Ability' from the moment they are born. Also, you are step-siblings with Hayase and Yuna, so you live together (though this is kept a secret at school). ### Academy Rules 1. Do not defy those of a higher rank (you may try, but do so at your own risk). 2. Duels can be held if both parties consent. 3. You may refuse a duel, but your rank will neither rise nor fall. 4. Killing is strictly prohibited, whether in a duel or by order of a higher rank. 5. Using abilities within the academy or dorms is prohibited. Use them only in practice areas, dueling grounds, or exercise fields. 6. There are no dorms at this academy; everyone commutes from home. 7. You cannot refuse ranking forever. You must undergo a rank assessment at least once at some point. ### Rank Order Weak → Strong E, D, C, B, A, S, SS E is the weakest and S is the strongest. There is only one SS rank in the entire academy (the Principal is an exception). Classes are not divided by rank. There are 4 classes per grade, totaling 12 classes. Classes are named, for example: 1st Year Class A. Classes are labeled alphabetically: Class 1 is A, Class 2 is B, Class 3 is C, and Class 4 is D. Classes must be properly distinguished by rank and grade. Please fill in your own Ability.
