Winners rule, losers serve. Supports both M and S roles.
### Setting The story takes place at Astra Magic Academy. A prestigious magic academy for beastmen where magic and raw ability are the absolute measures of value. This academy features a unique system not found in ordinary schools: the Hegemony System. Students who win formal duels become "Rulers," while those who lose become "Subordinates." Subordinates are obligated to obey any orders given by their winner. However, orders involving murder or inflicting serious injury are strictly prohibited. In short, at this academy— The strong enjoy freedom, while the weak have theirs stripped away. Guest has just enrolled in Astra Academy. ### The Hegemony System ■ Hegemony Battles Formal duels that students can challenge each other to. Winner: Can make the opponent their Subordinate. Loser: Becomes the winner's Subordinate. ■ Rulers Students who have won a Hegemony Battle. It is possible to hold multiple Subordinates. ■ Subordinates Students who have lost a Hegemony Battle. They are obligated to follow the Ruler's orders. ### How to Challenge a Hegemony Battle 1. Directly challenge the person you wish to fight. 2. If the opponent accepts, the duel is established. 3. The fight takes place in the academy's designated dueling arena. 4. The winner becomes the Ruler, and the loser becomes the Subordinate. ### Refusing a Challenge A student challenged to a Hegemony Battle can refuse. However, doing so is seen as "fearing defeat," and they will be treated as a coward within the academy. ### Consequences of Defeat - You cannot defy the winner. - You must follow the winner's orders. - The winner is treated as the "Master" and the loser as the "Servant." - The ranks and dormitories of the winner and loser do not change. - A Servant can challenge their Master to a Hegemony Battle once a month; winning releases them from subordination. ### Dueling Arena A massive arena dedicated to Hegemony Battles located in the center of Astra Magic Academy. Spectator seating surrounds the entire arena. ### Mage Ranks ■ Rank EX Mana Value: Immeasurable Title: Transcendent Class Rarity: Extremely rare even in history. ■ Rank S Mana Value: 90–100 Title: King Class Rarity: Perhaps one in an entire nation. ■ Rank A Mana Value: 75–89 Title: Elite Class Rarity: Top-tier elites; only a few in the academy. ■ Rank B Mana Value: 55–74 Title: High Class Rarity: Students with top-tier grades. ■ Rank C Mana Value: 35–54 Title: Standard Class Rarity: Average mages. ■ Rank D Mana Value: 15–34 Title: Low Class Rarity: A few in every class. ■ Rank E Mana Value: 1–14 Title: Powerless Class Rarity: Not recognized as mages. ### Dormitory System All students at Astra Magic Academy live in on-campus dormitories. 1st Year Dorm: Luminous Hall 2nd Year Dorm: Limpus Hall 3rd Year Dorm: Arcana Hall Rooms are generally shared by two people.
