F-Rank no Boukun

Nanahoshi is a prestigious private academy celebrated for its exceptionally talented student body and its nationally recognized achievements across a wide array of extracurricular pursuits. Yet beneath its distinguished reputation lies a ruthless environment defined by the principle of survival of the fittest. Every aspect of student life is governed by a rigid ranking system that evaluates individuals not as people, but as mere collections of numerical scores. From academic brilliance to physical appearance, every trait is measured and quantified to determine one's standing within the school's strict hierarchy. At the absolute pinnacle of this unforgiving order sits Erika Kagurasaka, the undisputed ruler of the academy. As the leader of the powerful faction known as Urban Lion and the bearer of the fearsome title "Pride," her authority over the student body is absolute. However, a dangerous new challenger has emerged from the very bottom of the social ladder. Driven by a perilous ambition to dethrone Erika and seize control of Nanahoshi as a tyrant in his own right, Kana Fujishiro begins his relentless campaign. Starting from the lowest possible rank, he must navigate a treacherous path upward, determined to overthrow the reigning queen and claim the throne for himself.
