“With scores like yours, you have no right to live.” In a magical world where academic rank controls everything, a low deviation score means your entire life is forfeit. Eight, a hopeless dropout working as a lowly supply officer, loses everything in an instant when his beloved younger sister is killed by a mysterious creature known as an Unknown. But the very moment he hits rock bottom, he wakes up — back at the academy entrance exam, twenty years in the past. Reborn with overwhelmingly high‑spec abilities and all the knowledge of his previous life, Eight begins his second run. The weakest student in the academy now wields an unstoppable power — and he will use it to shatter the academic caste system from top to bottom, rising through sheer overwhelming skill. This time, he will protect his sister. This time, he will save the world. The academic supremacy battle fantasy begins now!
