[Crossover] The Tenth Generation Doesn't Want to Be a Hero

Warning: One of the worlds in this story is My Hero Academia. The other two are superhero worlds and the original world. In 2099, Xia Zuo, also known as Sawada Yoshiki, is the great-great-grandson of the Tenth Generation. On the day he has spent four years as the heir to the Twentieth Generation, his family is destroyed. He thought it was inevitable, but just before he could take his own life, he was pulled into the space inside his ring. Then... What did he see? The decadent Fourteenth who gambles his life away, the kind First who feels like a loving father, the Valkyrie-like Seventeenth, and his best friends for life, the Tenth and Eleventh? The ancestors were nothing like he had imagined! From then on, a villain appeared in the world of superpowers. A villain appeared in the superhero world, too. And this villain, who was thoroughly unscientific in every way, happened to believe in science more than anyone else. This is really just a story about someone carrying his ancestors on his back as he transmigrates to different worlds, trying to save the Vongola family. P.S. The protagonist is ruthless, likes to go against the heroes, and often acts like a villain, but he's a good person (?). You know how it is. P.P.S. The author is sensitive, so please be kind QAQ New story, please add it to your collections!
