I Reincarnated as a Villainess, and Now I'm Affectionately Called "Big Sister"

https://www.cmoa.jp/title/282517/ Rinko Ariyoshi, the only daughter of a yakuza boss, was supposed to have died in an accident while protecting a child. But when she came to, she found herself in the royal palace, facing her time of judgment. She had been reincarnated as Adelina, the villainess in the otome game she was obsessed with, and in the midst of being accused of attempted murder of the heroine, she regained her memories of her previous life! What a mess, causing trouble for an honest young lady. In that case—! Rinko/Adelina, with her chivalrous heart, impulsively cuts off her own finger, but in the game world where magic is highly developed, her finger is reattached. In the end, Adelina is exiled from the country, stripped of her noble status, and forced to live as a commoner, but she could not hide the chivalrous spirit etched into her soul. Despite being reborn as a blonde, blue-eyed girl and wearing the frilly, girly dresses she loved in her previous life, she finds herself fighting off thugs in town, being admired as "big sister" by street kids, and before she knows it, she's walking the path of honor and chivalry!?
