学園の姫攻略始めたら修羅場になってた件

“Make me a princess!” One day, Yuma Kanbara finds himself in a tough spot, when his younger sister, Ayane, blackmails him with a certain cringe-worthy secret from his past. Her demand? To secure her a spot among the “Hime 6,” the prestigious titles awarded only to the top six candidates in Himegasaki Academy’s famous general election. Determined to claim the throne, Ayane leverages Yuma's weakness to make him “conquer” her rival princess candidates to clear the path to her victory. But winning over the school’s most captivating beauties is no easy task, and Yuuma struggles at every turn… Worse still, as he gets involved with the girls, he finds himself getting tangled up in the increasingly complicated romantic lives of the princesses themselves! With egos laid bare and love and scheming colliding at full force, the most chaotic romantic comedy ever is about to begin! (Source: Nico Nico Seiga, translated)
