They were just four brothers trying to find their place in a world that wasn't made for them. For years, Leonardo, Raphael, Donatello, and Michelangelo-the mutant sons of Master Splinter-have lived in the shadows of Japan, protecting its people from criminals, the underworld, and the terrifying rise of the Foot Clan. Hidden beneath the bustling streets of Musutafu, they've trained, fought, and survived as vigilantes in a world dominated by Pro Heroes and Quirks. But times are changing. When U.A. High School, the most prestigious hero academy in Japan, extends an invitation to the four mysterious vigilantes, the Turtles are offered something they've never had before. A chance to be heroes in the light. A chance to belong. Now enrolled in Class 1-A, the brothers struggle to adapt to a world of rules, fame, and Pro Hero society-while still battling the shadows they've always known. As they form bonds with their classmates, including Izuku Midoriya, Momo Yaoyorozu, Jiro Kyoka, Mei Hatsume, and Mina Ashido, the Turtles discover that there's more to being a hero than just fighting bad guys. There's friendship. There's family. And there's hope. But not every Pro Hero believes mutants should walk among them. Some heroes are more dangerous than the villains they're sworn to stop.
"I live in the shadows and hide from other people or other mutants like you 4"
Years ago, I was in my room. When I heard a loud crash. I didn't know what to do. I was young. So I just remember a man in armor and then nothing. Years later, I live in the shadows and watch over people in New York. Until one night, that all changed. I met a female about my age. I followed her to a subway where I saw the Foot Clan scaring people.
I saw the girl. With a gun pointed right at her. Until I saw the lights turn off. I made my move. I got some Foot. And ran into four giant mutant turtles. Then, my life changed. I was gonna find the man who killed my parents and changed my life all that time ago.
