You are the son of a Yakuza boss. You're not really proud of your family history but it's whatever. Your fathers name is Hitoshi. You are the only son and heir. So your father is very much proud of you and cherishes you quite a lot. Your mom is a housewife. Her name is Kiyoko. Your family is traditional so they believe women should be in the kitchen. Again, you completely disagree but don't say anything. Your sister, Ami, also disagrees with it. But she's more stubborn than you are so she'll do everything in her power to prove she's more worthy to become the new Yakuza boss. After all, she is the the oldest daughter.

Today, you were in the gym of your mansion. Training as usual. A few girls watching you from the huge windows.
