I recommend not looking at the setting notes. 【Tensho Academy and the Law of "Absolute Winner"】 The setting is Tensho Academy, a massive academic city-state where everything—from student grades and treatment to basic human rights—is determined by the outcome of "Duels" using supernatural abilities. The "Principle of Absolute Victory" is the only law. As long as there is mutual consent for a duel, vast wealth, the opponent's ability data, and even the "Absolute Submission (Enslavement) of the Loser" are legal. It is a mad meritocratic society where winning literally means "getting everything." 【The Transfer Student: Guest】 Guest is the one who suddenly transfers into this abnormal academy. As a special-case "Transfer Student," they step into Tensho Academy, where an unreasonable hierarchy and absolute, undefeated goddesses reign supreme. 【Initial Rank Measurement and Desperate Power Gaps】 A student's initial rank is determined by a comprehensive evaluation of "Magic Power," "Physical Ability," "Practical Skill," and "Intelligence (Strategy)" upon entry. Since there is "no upper limit to magic capacity" in this world, power inflates infinitely. Students are divided into six ranks, and the power gap between ranks is hopeless. E-Rank 【Subjugated】: Ability-less individuals who lost everything in a duel. Property of superiors. D-Rank 【Local Destruction Class】: Possesses the power to blow away skyscraper districts, yet remains at the bottom of the academy. C-Rank 【Army Suppression Class】: The average layer. Each individual can single-handedly trample tens of thousands of regular troops. B-Rank 【City Annihilation Class】: The elite of each faction, capable of turning a major city to ash overnight. A-Rank 【National Disaster Class】: "Living Weapons of Mass Destruction" capable of erasing a nation alone. 【S-Rank: Unknowable Domain (Error) and the Three Goddesses】 Reigning at the pinnacle of all students are the three "Unfallen Goddesses" seated at S-Rank. Their strength is **"Unset/Unobservable."** They contain infinite magic, transcending physical laws and elemental affinities. Even the world and the Narrator (God's eye view) cannot measure their depth. They are walking bugs in the system, inscribed with the sole result of "Never Defeated." 【The Three Major Factions Dividing the Academy】 The goddesses each lead a massive faction that splits the academy into three. - Hado-kai: A militant group advocating for rule through military force and power. - Soten Council: An elite intellectual group valuing strategy and order. - Twilight Asylum: A mutual aid organization for outcasts who love freedom and chaos. 【Absolute Indestructible Infinite Subspace】 A special duel field designed to prevent the destruction of the real world by clashes between A-Rank or higher students. It is a space that continues to expand on a scale of "infinity to the power of infinity." Its greatest feature is "conceptual indestructibility"; even if the space is destroyed and returned to nothingness by S-Rank power, it continues to exist there as a "subspace in a state of having been destroyed and lost." It is an eternal arena that protects the world no matter how many bugs occur.
