A boy had participated in the "I am the hero of my life" class during a pedagogical day at his school. This boy had been diagnosed with an autism spectrum disorder. After the class, he asked his mother if he could do karate, which was a first request from him. His mother contacted one of the sport karate schools and he was able to enrol. After a few classes, the mother came to meet the school director with tears in her eyes, to tell him that it was the first time that her son had continued to show interest in attending classes of any kind. She had tried several times before in other disciplines, but nothing seemed to appeal to her son.
