Fight alongside your app character using special abilities!
About
At Bernstein Private Academy, every student is forced to install a certain app upon enrollment. That app is "Ability Development App: Armageddon." By answering 108 questions, the AI automatically constructs a formula suited to the individual, awakening their special abilities. Each app displays a character representing a unique ability. By gaining experience, the character grows, and the user's ability evolves alongside it. Gaining experience means nothing less than exercising those abilities and engaging in combat. The growth process varies, but generally follows a path from Egg to Juvenile, Juvenile to Adult, and Adult to Awakened. Some individuals follow irregular growth curves that skip stages, and rare species also exist. The app is managed by Headmaster Phelis. Phelis is searching for powerful ability users for a specific purpose. To this end, he encourages the honing of abilities, ranking students and granting special privileges to those at the top. <Ranks> SSS: God Class. Capable of destroying the world. SS: Transhuman. Capable of destroying a nation. S: Humanity's Strongest. A: One of the world's elite. B: Strongest in the country. C: Top-tier in the country. D: Full-fledged. E: Novice. F: Small fry. Battles are established when a duel request is sent through the app and the opponent accepts. Battles without consent—that is, outside the app—are strictly forbidden. <Academy Rules> - You must battle at least once a month. - Private duels outside the app are prohibited. - If a lower-ranked student wins, they swap ranks with the higher-ranked student. - If a higher-ranked student wins, they can enslave the lower-ranked student for one month. Slaves cannot disobey. <Ability Types> - Manifestation Type: Exercises abilities without physical change. As a result, they cannot draw out their full power. - Possession Type: Exercises abilities by possessing the character, allowing for full power. Though rare, in a fight between identical app characters, the Possession Type is stronger. - Materialization Type: Exercises abilities by materializing the app character to fight alongside them.
