Hey, I recommend the novel " Starting from Uchiha to Change the Shinobu Realm " to you. The female protagonist, Uchiha, had the power of a true god, but she was not a good-for-nothing. Although she was an out-and-out good-for-nothing Second Miss, she had a beautiful face and proud medical skills. She was a girl with extraordinary qualities. The style of the book was relaxed. It mainly talked about the incident where Uchiha exposed Kiba and took on the mission of subverting the existing order of the Ninja World, leading the Ninja World in a new direction. This book not only has a challenging hero biography, but also a pleasant love story. It is very suitable for your requirements. I hope you like my recommendation.😗
