Medaka Box Gaiden: Good Loser Kumagawa

Misogi Kumagawa's life at Suisou Academy is defined by one simple, brutal rule: he must lose. As the self-proclaimed "Greatest Loser," he has endured over 10,000 consecutive defeats, a streak meticulously enforced by the school's enigmatic and powerful student council president, Saki Sukinasaki. His existence is a perpetual cycle of humiliation, designed to break his spirit completely.

This status quo is shattered when Kumagawa, driven by a twisted resolve that even endless failure cannot extinguish, issues a challenge. He declares a one-month-long battle against Sukinasaki herself, aiming not for a petty victory, but to overturn the very system of absolute defeat she represents. Their escalating conflict becomes a war for the soul of Suisou Academy, a clash where the only acceptable outcome for Kumagawa is to become the ultimate "Good Loser" by destroying the concept of losing altogether.
