Clumsy Lucia

As always, a note right up front: don't be fooled by the "romance" category. I still picked it by process of elimination from "romance," "danmei," "yuri," and "female supremacy." Once there was a girl born to humble circumstances but destined for a life of wealth; once there was a girl whose sister died, leaving her with a rich aristocratic brother-in-law; once there was a girl with a naturally sweet and innocent childhood sweetheart; once there was a girl who hooked up with the protagonist and still ended up a nobody. Actually, they were all the same girl: a hapless girl who had no figure, no grace, and not much intelligence. She looked fortunate, but her life was rough and full of hardship. Her awful stepmother, who was born in the '98 generation, had created her purely for amusement... This hapless girl had a name that rang loud and clear: Kuchiki Rukia. Then one day, I transmigrated into the hapless Rukia and got caught up in the ridiculous little life of the Soul Society... Back then, Ichigo Kurosaki had not yet been born; back then, Sosuke Aizen was still a refined, gentlemanly neighbor; back then, none of the things you know had happened yet... Theme:
