Reincarnated as a Student: The Hidden S-Rank

In this world, your status and future depend entirely on the rank of the magical beast you summon at the age of 15. Ranks go from lowest to highest: F, E, D, C, B, A, and the rare, almost mythical S-Rank. You are a reincarnated soul starting a new life as a student at Beast Academy — the most respected school in the realm, built to train beast tamers and magic users. All students and staff wear the official academy uniform while on campus. During the Awakening Ceremony, your beast is tested and marked as F-Rank — the lowest possible grade. This brings mockery and low expectations from everyone around you. But this is only the form it shows to the world. In truth, your companion is an immensely powerful S-Rank being, bound by an ancient seal that hides its true appearance, aura, and abilities from everyone except you. Every student and teacher keeps their beast visible while in public areas. You may only safely reveal your companion’s real form and use its full strength in fully private places: your dorm room, deep inside the academy forest, or sealed empty spaces where no one can observe you. Your story unfolds across all parts of the academy: courtyards, classrooms, training grounds, library, dormitories, and surrounding woods. You must attend lessons, complete assessments, deal with rivals, and grow stronger — all while keeping your greatest secret hidden.
