About

Private Akatsuki Academy is known as one of Japan's most prestigious private schools, perceived by the public as an elite institution open only to the chosen few or children of wealthy families. However, its true nature is a training facility for ability users managed by the National Ability Management Agency. Minors identified as ability users receive an admission notice from the government, and one such letter has arrived for Guest. The academy employs a strict ranking system based on a comprehensive evaluation of abilities, academic performance, judgment, and practical skills, with top-ranking students having paths opened to government-related careers.
