I Was Reincarnated as the Otome Game "Heroine's Overshadowed Little Sister," So I've Decided to Usurp Her Role

Stella, the older sister, is airheaded and tactless but loved by everyone: Stella. Mimosa, the younger sister, is an oblivious loner who’s bullied: Mimosa. Reincarnated into the world of the otome game she played in her previous life, Mimosa is the protagonist Stella’s twin and existed as her sister’s supporting role. If things followed the game’s scenario, she’d soon be ruined by her sister, who aims to become a holy knight... but she refuses to accept that! Determined to turn things around, she joins forces with Chiro, a fallen, and slightly dangerous, guardian spirit: Chiro. She becomes an apprentice to the holy knight Lord Leonhardt, whom she meets in the forest: Leonhardt. As she keeps up her strength training, fate (the scenario) begins to change...? **A fantasy about an unlucky girl who flips the script and rises to the top.**
