Find an anime where the main character looks like a good-for-nothing but is actually very powerful. Every time the female lead is in danger, he will save her, but the female lead doesn't know it!

I'm not sure which novel you're referring to. If you can provide more context or description, I will try my best to provide you with a more accurate answer.

Kirito, the male lead in the Sword God Realm, was a seemingly useless but actually very powerful character. He was an ordinary university student who usually looked very ordinary and didn't even have many friends. However, in the face of life and death, he displayed amazing strength. In the SAO game, he gained a powerful ability to control swords to attack and defend. At the same time, he also learned many skills such as invisibility and teleportation. Although his combat ability was not the strongest, he was always able to come up with a unique way to solve problems and face challenges and ultimately win.

I recommend the novel " A Trash Mother's World-toppling Country Estate " to you. The female protagonist may seem like a loser on the surface, but she's actually capable. Her fiancé broke off the engagement and was chased out of the house. She started her own business and created her own world, becoming the richest person in the world. The plot of the book included villains and conspiracies of relatives. The female protagonist gained the upper hand through her own ability and hard work, and finally obtained happiness.

Many anime works had powerful female protagonists, such as Allen in Attack of the Giant, Kirito in Sword Art, and Tanya Shangjo in Forbidden Magic Books. These female protagonists often had unique abilities and strengths that could make a significant contribution to the development of the story. At the same time, their personalities and experiences were also very rich and impressive.

Kirito in the Sword Art Online was a female protagonist who had the ability to communicate with the world of SAO and played an important role in the story. Alan Yaeger was also a female lead in Attack of the Giants. She was one of the protagonists of the story, with strong combat ability and wisdom. There was also the female protagonist in The Stone of Destiny, Grella Griffin, who could manipulate the flow of time and change the present by finding the mistakes of the past.

Yes, I recommend the book,'Female Supporting Character Asking Immortals' to you. In the book, Jiang Wu transmigrated to become the evil second female lead, but she did not do it to snatch the male lead or destroy the pairing. Instead, she did it to protect herself and make a living. She was forced to lie to the male protagonist, but after the misunderstanding was resolved, the male protagonist, Xiao Qinghan, unexpectedly protected her. Jiang Wu was moved by the male protagonist's kindness and developed feelings for him. Therefore, the second female lead in this book isn't snatching the male lead or destroying the pairing in the traditional sense. Instead, she's an awesome second female lead with her own story. I believe you'll like her very much. I hope you like my recommendation.😗
