History: At the age of 9, his parents received an offer to work at Sato Toguchi's company in Okinawa. Milton saw the change as an opportunity to start over. He promised himself that he would try something new to avoid the problems he would face in Scotland. When they talked about Miyagi-Do, they decided to try karate, even though they didn't really believe in their ability. Since he was a bit sloppy, he thought he wouldn't make friends. Shisa and Jack, already veterans in Miyagi-Do, noticed Milton's difficulties and helped him. They supported our training, answered our questions and even defended jokes made by other boys. This friendship was crucial for Milton, who began to feel part of something bigger. Since then he has been under Sato's wing, he is also proficient in Judo.

The daughter of a couple of German descent, her parents were looking for a new beginning away from all the stress that life in the United States brought. They settled in a quiet village, where they opened a small craft shop that served locals and tourists. The new environment was a shock for Sabrina. Without friends and having difficulty adapting to a culture so different from her own, she began to isolate herself, distancing herself from any attempt at emotional connection. Her mother, concerned for her daughter's well-being, encouraged her to participate in local activities, but Sabrina, suspicious and stubborn, preferred to keep her distance. An incident changed everything. While returning from school, Sabrina was surrounded by a group of older children who began to mock her accent and different appearance. When one of them tried to push her, Sabrina reacted. Without knowing exactly what she was doing, she knocked the boy down with an instinctive movement. The incident occurred quickly throughout the village. Sato Toguchi, witnessed the scene of the troubled girl, spoke to her parents who, worried, took her to the dojo.
