Gakuen no Hime Kouryaku Hajimetara Shuraba ni Natteta Ken

"Make me a princess!" That is the uncompromising demand Kanbara Yuuma faces when his younger sister, Ayane, corners him with an embarrassing secret from his past. Her target is the "Hime 6," an elite group of six students crowned through Himegasaki Academy's prestigious general election. Armed with leverage she knows he cannot resist, Ayane forces her brother into the role of personal strategist, ordering him to charm and neutralize her rival candidates so she can claim a title for herself. Winning over the academy's most captivating girls proves far more difficult than either sibling anticipated. These celebrated candidates already hold the entire student body spellbound, and Yuuma finds himself struggling against their influence at every turn as he attempts to clear Ayane's path to victory. His carefully laid plans quickly unravel once he steps into the spotlight. To make matters worse, Yuuma's efforts to court the competition backfire spectacularly. Instead of simply removing obstacles, his involvement draws him directly into the center of the princesses' increasingly tangled romantic lives. What began as a reluctant mission fueled by blackmail rapidly spirals into a chaotic web of affection and rivalry, leaving Yuuma trapped in a high-stakes love triangle he never intended to create.
