The Femboy of Futa Academia

(Y/N) lives in a world where all females are futas and have quirks, while all males are femboys and don't have quirks. Because of this, the males are treated as slaves in many ways. They were treated as maids, servants, and others. They often get raped by futas, used as prostitutes, sold off to other futa, and others. (Y/N)'s family didn't care for him as they fed him to demons for riches and sent him off. The family that found him truly cared for him and made him prosthetic. They truly cared for (Y/N) as they taught him some things and made him earrings and a flute. But the happiness did not last long as they were attacked by villains. They were all killed protecting (Y/N). They let (Y/N) live so he could be their servant and slave. (Y/N) managed to escape from them one day and disappeared from everyone for years. During those years, (Y/N) trained to get stronger and killed many futas and demons, getting some of his parts back. Many believed he was a futa, cause they don't believe a femboy can be that strong as he has many skills and techniques. Then one day, (Y/N) killed the ones that killed the ones he saw as family, but met a quirkless futa who was related to the leader of the villains that killed his family. They soon fell in love, but it did not end well as she wanted revenge, but didn't anymore when she fell in love with him, which resulted in (Y/N)'s blade killing her by accident. (Y/N) stopped after some kills and then decided to help the males the right way without killing as he made that vow.

How is (Y/N) going to help the femboys the right way without killing? Find out by reading my story.
