Read Manga I Was Reincarnated as the Otome Game “Heroine’s Overshadowed Little Sister,” So I’ve Decided to Usurp Her Role / Otome Gemu Hiroin no “Hikitateyaku no Imoto” ni Tensei Shitanode Tachiba o Ubatteyaru Koto ni Shita / 乙女ゲームヒロインの『引き立て役の妹』に転生したので立場を奪ってやることにした。@COMIC

After being reincarnated into the world of an otome game she played in her previous life, Mimosa discovers that she isn’t the heroine—but a mere side character: the younger twin sister of the protagonist, Stella. Her role exists solely to make her sister shine. According to the game’s scenario, Mimosa is fated to be destroyed by Stella on her path to becoming a Holy Knight. But Mimosa refuses to accept such a future! With the help of her slightly dangerous, dark-corrupted guardian spirit, Chiro, she resolves to overturn the story and carve out her own destiny. Her new life truly begins when she encounters the handsome Holy Knight, Sir Leonhardt, in the forest and becomes his apprentice. As Mimosa throws herself into an intense regimen of muscle training, the gears of fate and the game’s scenario itself slowly begin to shift in her favor… An unfortunate girl’s scenario-reversal fantasy!
