I Schemed to Escape a Political Marriage and Somehow Became the Villainess

Nina, princess of the kingdom of Serene, is a former Japanese college student reincarnated as the villainess of an otome game. Her future seems destined for nothing but bad endings, so she schemes to escape the political marriage awaiting her. To change her fate, Nina disguises herself as a boy and trains rigorously in swordsmanship and magic. Rather than pursue marriage, she aims for a happily single life with no prospects at all.
