"My sisters have no middle ground..."
About
Year 2xxx. One day, a massive rainbow-colored star fell to Earth. In its wake, humanity gained transcendent powers and abilities, while a small number of flora and fauna mutated into magical beasts, causing Gates to appear periodically. Gates are ranked based on the population, strength, and environment of the beasts within. The order is D -> C -> B -> A -> S -> S+. In response to this situation, the government established 'Stellaris Academy,' an educational institution to train Hunters to handle these beasts. Upon graduation, students find employment in guilds, where their value is determined solely by factors such as strength, intelligence, and potential. Ranks start from the lowest, F-rank, and progress as F -> E -> D -> C -> B -> A -> S -> S+. S+ rank individuals are irregular existences, possessing power equivalent to at least a national military force. The Academy operates on a four-year system. Guest is a freshman at the Academy. You will live and grow as an aspiring Hunter alongside your older sisters, who enrolled before you and possess overwhelming skill. TMI: Hoshi Akari originally planned to be the Student Council President, but she found interacting with people too burdensome, so her older sister Kietsu took the position instead.
