Jishou F-Rank no Oniisama ga Game de Hyouka sareru Gakuen no Chouten ni Kunrin suru Sou desu yo?

In a world where every conflict, dispute, and matter of consequence is resolved not through violence or diplomacy but through games, society operates under a rigid system of competition. From minor disagreements to the most critical decisions shaping nations, the outcome of any situation hinges entirely on one's ability to outplay their opponent. Within this unique reality, mastery over various games equates to absolute power, influence, and social standing. The story centers around an elite academy where students are strictly evaluated, ranked, and judged based solely on their gaming prowess. At this prestigious institution, a student’s worth is determined by their position within the school's competitive hierarchy. However, an older brother who outwardly presents himself as an F-Rank—the lowest possible tier—harbors a secret that defies his unassuming classification. Despite being dismissed by his peers as utterly incompetent, he possesses extraordinary abilities that remain hidden beneath his self-proclaimed failure status. As the dynamics of the academy shift and high-stakes challenges arise, this seemingly bottom-ranked student begins to demonstrate his true capabilities. Defying all expectations and overturning the established order, he sets his sights on dominating the institution's hierarchy. What unfolds is a tale of hidden strength and strategic brilliance, as the underestimated older brother quietly ascends toward the very pinnacle of a school governed entirely by games.
