Although Ouyang Muchuan had good grades in school, he was always bullied by the school bully because he was a poor man. Finally one day, the rich school bully wanted to hire someone to kill him. Just before he died, a mysterious force tore apart time and space and injected it into his body. He transformed into Kamen Rider Den-O/DEN-O. From then on, he walked around the school and was called "Grandpa Lao Lao." It didn't matter if he was poor. In the face of absolute power, all wealth was nothing. It was so rampant!
