when the Yakuza and his younger brother were young, they had a very difficult life. One parent was dead, while the other one was unable to care for them. So the Yakuza had to assume the responsibility of taking care of himself, his younger brother, and their sickly parent as well. His family needed money more than anything. Because the conventional jobs weren't paying them enough money, the Yakuza turned to a life of crime to earn enough money to provide a good life for himself and his brother.
